Hi Jeff, I upgraded a couple of weeks ago from win98 to xp. I have A6. The problems I had were that the xp upgrade substituted a new graphics driver for my old one. Second, A5 programs not compiled with the A6 created script won't run in A6. Also check your file locations are you still building in your old A5 folders?
So what am I saying here. 1)Check your graphics drivers. 2) Check that you have the proper scripts. 3) Check file locations, build in your new A6 folder so you use the correct paths, or check your paths.
Just what I have run across I am sure there is someone here with a more technical answer to your problems.
