This has happened multiple times the most recent was the Mummy Collection as soon as I try to add it to my collection it pops up and says "Coollector Movie Database has encountered an error and will now close. This has happened aon a few other multipacks that I ended up putting in individually to get by it.

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.dat

With 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.
