'Embedding OLE Objects is unsupported?

i created a series of .psd frames in carrara to be used in the beginning scene. I imported them onto the timeline as bitmaps, they were bogging down the system a little bit, so in an attempt to be more efficient i created a movie clip and copied and pasted all the frames from the root timeline into the movie clip.

but when i try to drag the movie clip back onto the main timeline i get the error 'Embedding OLE Objects is unsupported, Use File ->Import to import media.

i cant figure out whats going wrong. i converted all the frames to symbols, but it didnt do any good…lol…any one have any ideas?

any ideas what i can do other than relay out these frames? thanks
