Download from Cloud, launched successfully. Took some type and changed the scale, hit preview, watched the green bar grow, hit play and nothing happens. What am I missing. Worked fine in AE5 and 5.5. I did turn off mutliprocessor, clear cache and try,then tried with multiprocessor on and still nothing.

I'd try the same in a new comp and see if its something native to your original comp. Also, make sure your window is in active Camera. Also, see if its a scaling issue or a RAM issue by changing another attribute in the comp, and see if it previews. If its a RAM playback issue, then tackle the ram playback settings.
