Ok, I am completely stuck.

I have added a big amount of ebooks to Calibre (in 200-800 steps).
Suddenly I could no longer open Calibre.
Whenever I tried I got the error message (programme had to be closed, sorry for inconveniance etc.).

Well, ok. I downloaded the newest version (1.18) and installed (overwriting the existing programme).
Same result.

I downloaded the newest portable and installed on another harddisc. This works fine but it is not possible to switch the library to the old one.
This library is really big (approx. 112 GB+).

I thought that maybe it will work if I put the library on a disc that has only few data yet so I copied the library folder to the disc with the portable Calibre software and tried to switch library again.
Not possible.

There is nothing happening, Calibre is not responding (even after hours) and/or I get an error message.

What else can I do now?
I have a backup of the Calibre profile as well as library which is some weeks old - way before I tried to add the amount of ebooks.

Could it be a problem with the metadata_db?
The software itself seems to be ok otherwise it wouldn't work after installing and with just 1 file in its library.

Should I completely delete the original Calibre programme, install new and try to direct it the library folder (but I can't imagine that this will help)?

OS: WinXP, sp3
Pls. no "you must upgrade to Win7 or 8". It is not possible now. I know that XP is outdated but Calibre worked (more or less fine) with it until recently.
