Hi Tim,
I have actually managed to solve the issue. I was opening projects created in V12.2 and letting AE V13 convert them. Then without saving the converted project I was trying to do a RAM preview and getting the error (a screen shot of which is attached). However if I save the newly converted project and then reopen both AE and the project I get real time play back?
Weird but workable.
Thanks for the help
Nic
