Okay here's the whole story, I have a whole bunch of sequences in a premiere file that I'm working on and each sequence needs a after effects comp. I started to link my comps and get to work on my laptop running windows 8, the latest premiere and After effects and it works fine. Then when I move over to my desktop (by the way all of my work is on a protable hard drive that I work on) I link comps on my desk top and the after effects linked comps aren't working. My desktop is running windows 7 and the latest premiere and after effects. But when I click on "replace with after effects comp" it comes up with after effects, the timeline is as long as the clip, there's nothing in the project window other then the comp. I've looked ALL over the place for a solution to this problem, apparently this problem has been around since the CS3 days, but I hope someone can come up with a solution to this. Cheers All!
