We use neither a registry key nor a My Account, so I am not sure what you mean.
For installing Gamestudio, download it from the download page, and copy your key file into the installation folder for unlocking it.
Thanks jcl. It had been so long I didn't remember you just had to copy the key file to the folder, I mistakenly assumed it was a registry key. I'm sure this must be documented somewhere, but I couldn't find it.
The My Account was where I ended up in search of retrieving a new key from (I believe) your payment gateway. Which was probably another mistake, but it's where I ended up at some point during the search.
Anyway, thanks for the answer. I copied the key file over and everything is fine...
