Not sure if this is the correct place to post, but I couldn't find another area suitable. I recently purchased Gamestudio A7. I installed it on Windows Vista. I have since upgraded to Windows 7 (fresh install, not really upgraded). I took the ack6e.key that was sent to me via email and tried to run it in 7. Windows gave an error saying that it did not understand the file type. I tried to open it with regedit.exe and it said that it was not a valid binary key. However, after installed gamestudio, I opened it up and it did say that it was registered to my name, so I'm not quite sure what is going on. Just wondering if I need to request a new key for Windows 7 and how to do so. Thank you for any responses.
