Thank you for the response.
To claify my problem, I can open a project in CS5 OK. The sequence and clips come up, and I can manipulate the, eg, resize a still image,
change in/out points on a clip, etc
When I click on ">" to play the program, it stops after a few seconds. Repeating the "start" comand getrs the same
Perhaps this info is some help
