It seems like a lot of people are having trouble when upgrading to a new version of FPSC and losing their user information.
If you have encountered this problem, here's what you do:
1. Navigate to your FPSC directory, usually C:\Program Files\The Game Creators\FPS Creator
2. Open up userdetails.ini.
3. Fill in the correct information into the YourName and YourSerialCode fields. Do not change any other information.
4. Your file should look like this:
[PERSONAL DATA]
YourName=Some Guy
YourSerialCode=ASerialNumber
YourFullPath=C:\Program Files\The Game Creators\FPS Creator
[LOCALIZATION]
language=english
