I'm having the same problem, but on WinXP SP2. After I designate the folder, the GUI very briefly appears with the migrating dialog on top. I tried all the suggestions on the page you cited, but no go. Here's the output from debug:

C:\Program Files\calibre>calibre-debug -c "from calibre.gui2.main import main;
ain()"
Traceback (most recent call last):

Hmm regression. I'll upload a fixed build in an hour. Re-download and try again.

I am wondering if you have considered moving to some type of two stage release schedule. I notice that alot of times there are regression... which I under stand. But, it seems that every new build you release I am notified about it. I wonder if now that this software is so popular you might consider having your auto update and versioning scheme be set up so that auto-update notices are only sent out for "stable" versions.

There are several other open source projects that do something like this. That way, people that want to get your betas or whatever know that there may be a problem. Once you have had a version out for a while and fixed any bug reports you then release it as a stable version.

I know you don't do this for a living... but it might save you some time in the forum and also it will save new users from seeing alot of regression or other bugs.

Just a suggestion.

Actually I was just thinking about moving the auto update notification to even numbers only. The only concern is that I'm sceptical as to how much testing odd number releases will actually recieve without the update notification. I doubt there are many people that actively keep an eye out for calibre updates. This way atleast when critical bugs are identified I can fix them in a jiffy.

Part of the reason that calibre has made so much progress so quickly is that I release buggy code, and get my users to do the testing for me. If I started to wait for code to "stabilize" the pace of development would inevitably slow down.

It's a tradeoff, and I'm not sure where the sweetspot is.

I'd suggest simply changing your version numbering (Currently you're using A.B.C)

Quite apart from the issue of A=0 (see [1] below), either incrementing the 'B' for features or splitting the 'C' into 'C.D' and differentiating the feature change releases from any bug-fix releases would allow users to estimate & judge the chance of issues in any particular release.

Hi - Were you able to upload a new version? The latest I see is still 0.4.103 (the one I had the problem with). No rush!

He said he would fix the build... I don't think he meant it would be a new version. So the fixed build is still version .103.

If you ask me (and you didn't :-) version numbers are cheap and should always be incremented to prevent confusion...

Anyway, I downloaded the new build and while my initial problem is no more, the application now hangs (and consumes all my CPU) when I try to open an html formatted book (converted from .pdb using ereader2html).

version numbers are cheap, but asking users to download a new version with a single bugfix is not.

Give it a little time, calibre now parses html files, follows all links in themand creates a zip file automatically on import.

Well, we'll have to agree to disagree about the version numbers. I'm a long time build and configuration management guy. Anyway...

Patience paid off and it did complete. Perhaps you could add a progress indicator?

The resulting lrf came out pretty good with just the default settings. However, the last line of every paragraph was centered between the margins. I couldn't find a setting to [left?] justify. Any thoughts?

Thanks for all your help!

I was able to resolve my problem of the last line in each paragraph being centered by following the advice in this thread:

last line in each paragraph centred

I used MS Word to load and resave the html file (without modification) and the convert went fine.
