I go through this myself. What you do is change the size then start the program and change the size back to where you want it. This bypasses the built in size checker. As far as I know there is no way around it.
They call this lazy programmers :rolleyes: If they built the program around 800X600 then size change would be normal like most other programs. They knew they were being sold out to Sonic so I doub't they cared anymore.
ps: cd key I have no clue. Should have come with the disc or in the download from Roxio. As I recall the key was sent as an email.
Don't try v7.5 or V8 nothing but trouble with other programs.
