Hello all,
If any of you were lucky enough to buy the FPSC Bonanza (like myself

) and for some reason after updating found out that it was FPS Creator Free without any way to enter your serial other than buy that "Build Game Upgrade" thing for 2000 points or whatever here's what you got to do:
Close FPSC and go to your userdetails.ini (for me this was located at C:\Program Files (x86)\The Game Creators\FPS Creator) and enter your registered name and serial code. Then restart FPSC and it should be back to full version again.
Just my 2 cents to help out the community, sorry if this was posted beforehand. Enjoy!
