Problem Converting CBR to Epub

[Judosailor]

Hi,

First, thanks for such an amazing open source program. It's great and I love it.

However, after upgrading the latest version of calibre 64 bit, it will not longer convert CBR files to anything (I tried both Epub and pdf). Here is the error log from a CBR file I tried to convert. I am running Windows 8 and have the latest version of Calibre.

Spoiler:

calibre, version 0.9.31 (win32, isfrozen: True)
Conversion Error: Failed: Convert book 1 of 1 (Age of Ultron 008)

What's even more interesting is that I went back to a CBR file I had previously converted to Epub using Calibre. I deleted the Epub and tried to convert it again and it failed. Here is the error log from that conversion.

MemoryError

Finally, I realize the last line says there is a memory error, but I believe there is nothing wrong with my computers memory. It is only a few months old, has sustained no damage that would hurt it, and is experiencing no other problems.

Thanks

As it turns out it must be an issue with the 64 bit version of calibre in Windows 8. After finding another thread where a guy had the same problem, he said the solution was to use the 32bit version of calibre. I switched, and now it works fine.

Converting cbr files with the 64bit version of calibre works for all the cbr files I have. If you have some for which it fails, post a sample.
