Have tried changing the project playback to mercury engine software only as suggested in another thread.
But as soon as I try to browse for files it crashes.
I have wasted at least a whole day on this.
Meanwhile I have bought Sony Vegas - so don't worry about extending the trial.
Try to start the program as an administrator, right click on "Run as administrator" to see if the problem persists.
Still having trouble, TonyP? Let us know.
