After Effects CS5 timewarp troubles

Question

Hello all,
Was hoping someone could help me out with a wierd problem I am having trying to apply timewarp with after effects CS5.
I have previously used it for high quality slow motion using the pixel motion option in PPro CS4. Heres what I do.
While in PPro CS5 i would select the small portion(clip) I wish to apply the timewarp to and use the "Replace with after effects composition option." This opens the clip in after affects as normal and is fine at that point. My selected clip appears on the AE timeline ready to play with. Now....
When I apply the "Time Warp" effect, the clip on the timeline changes to a completely different one. I don't mean it changes to a different point on the clip that was imported, I mean it changes to a completely different clip where the footage I wanted to apply it to isn't even available. As soon as I delete the time warp effect the original clip returns. This has happened to me now on my last 3 projects.
If anyone has any ideas where I may be going wrong I would appreciate it. But as it is at the moment I can't use timewarp.
Thanks
John

This is in reply to OP J Maggs and RustedX:
Hey guys I feel your pain. I am taking the time to reply just because I had the SAME problem and researched all over the internet and wasn't available to find much specifically about my case which it seems to be EXACTLY what happens/ed to RustedX.
I've got a 16 seconds clip, shot with a Canon 7D at 1280x720 60fps. I wanted to slow it down to 5% with After Effects CS4's Timewarp. So, because I tried the same effect with Apple Motion (with success), I knew the new time of the clip was going to be 5:30 minutes long. So I changed my comp time from 16 seconds to 5:30 minutes. I dropped the clip in to my comp timeline (which showed me a little 16 seconds clip into my 5:30 minutes comp) and applied the Timewarp effect to my new layer. It did slowed it down but still the clip on the layer was at 5% but only for 16 seconds. Meaning it should had been a 5:30 minutes clip, but stayed slowed down at 5% for only 16 seconds. So, I sent to render because I thought 4gb or ram probably wasn't enough or something, and it came out a nice 5:30 minutes long clip with 16 seconds of slow motion at 5% and the rest of the clip is completely black.
I wasn't UNABLE to extend that @#$%!V little clip on my time line. I used all the methods I know (even the ones posted at http://help.adobe.com/en_US/aftereffects/cs/using/WS3878526689cb91655866c1103906c6dea-7e70 a.html [although are for CS5]), but I had no luck. I am not sure, perhaps I did not perform those properly.
It took me almost 3 days of research now (in and out of course), but finally I found a solution (at least for my case) and I am posting it here now in hope it will help more people with the same issue.
What finally worked was this:
I selected my layer with the clip on my timeline, and I right clicked on the layer not the comp and selected Time -> Enable Time Remapping
And voula!
My layer with the clip was extended all the way until the end of my comp and was able to preview the results as I was scrolling over the time line.
My goodness, finally! What a relief after all those hours of surfing the web for an specific answer
Oh well, I hope this helps some else!!
Have a great Timewarping guys!!
