Thank you very much for reporting this bug !
I'm sorry, but when we've built the version 2.94 of the database, there was a bug that has corrupted all the technical details of all the packs. I have discovered that only recently, and I thought that it wasn't too big an issue. Now that I know that in some cases it can make the program crash, I will release version 2.95 as soon as possible.
In the meanwhile, you can download a fixed version of the database to replace the corrupted one:
http://www.coollector.com/english.movies.datWith XP, you'll find the database inside Documents and Settings\All Users\Documents\Coollector\Databases\
With Vista and 7, you'll find the database inside Users\Public\Coollector\Databases\
I apologize for the trouble.
