I do have the installer and the reg key for the versions I paid for and currently it works fine as a 32-bit vst. When I discovered a while back that the 64 bit version was missing on my system for some reason I couldn't find the installer info so I signed in to my account to get the installer again and my licences are gone. I thought somebody had maybe hacked the account and done something so I contacted them and they said that they had removed them and that I would have to upgrade to the new versions to get them back.
I later found my original installer info, but now I'm wary of installing the 64 bit version in case it messes the existing authorisation up and then I will have nothing at all and because their newer version demos overwrite older versions I couldn't try them if I wanted to now without being forced to buy them, so I go with what I have and will replace them with other products as I don't appreciate being held to ransom.
