Hi bought the pro edition, but I am having trouble updating. After failing to overwrite what seems to be my standard key, I reinstalled gs. If I then unzip my pro key.exe, it does nothing. It still says trail version. It seems to lack a dll file that my standard licence contained in the zip. I have the 6.1 installer and need to work with 6.3. Do I absolutely have to work with the new version of gamestudio, which is the only thing I can think of to be the problem.
