Hi, I'm trying to help my boss out. In the past, he had previously used Sound Forge 10 trial version, then 11, then 16. He decided to buy the full version of 10 but is getting a message telling him to upgrade to the paid version or enter his serial number. Every time he enters the serial number associated with his purchase (bought from Amazon), it says that it attempts to upgrade and closes the program, but then the same message pops up. I attempted to do the same thing from my computer, using his Amazon login and the same serial number, and I was able to download and launch the program without issue. This is extremely frustrating and time-sensitive, as he needs to have access to the program ASAP to update tracks for his radio show. I am wondering if having the trial version previously is messing with his permissions to upgrade or something but if anyone can provide any help, it would be much, much appreciated.
Edit: he is using a Windows OS.
