Completely uninstall A6 including deleting the folder. Make sure to BACKUP anything in there you don't want to lose. After that, reinstall the A6 demo and then install the key.exe contents into the newly created GStudio6 folder. Then, download the 6.6 update and let it do it's thing.
If you've lost your key and password then....

Q. I've lost my key disk or key file, and forgotten my password. Can you send me another key file?
A. If you still have a valid Gamestudio installation, you can re-build your key file. It's a ZIP archive containing the files password.txt, ackutl.dll, bin\ackutl.dll, and bin\acknex.exe in your Gamestudio folder. You can find your password in the password.txt file.
If all is lost, you can order a new key in our online shop. Please give your name and address, and the original purchase date.
ALWAYS back your key.exe file to CD/floppy and keep it someplace where it isn't going to get lost or stolen.
