Not sure why. I have been using it for the last year with no problems. Then all of the sudden, if I try to burn a large game, when I load the gi file I get a Run-Time error 9 Subscript out of range. So I download the latest engine update PxEngine358 and now I can't even run the program. When I try to load it, I get the same error. I tried to uninstall and re-install the orginal version, and same error. So now I can't evern load Prassi PrimoDVD 2.0 at all. Can anyone shed some light to my situation? Thanks.
