How did you export?
Also, do you have AE on this machine?
To export, I did: File > Export > Adobe Premiere Pro Project...
And yes, I have After Effects on the same machine as Premire Pro.
Even though a lot of effects appear in both Premiere Pro and After Effects--even with the same names--they're not entirely compatible. Only some effects, and very few at that, will make the trip from one application to another. The PPro help docs outline what you can expect to travel intact. You will likely need to remove all of the offending effects in AE before you attempt the project transfer, and then replace them in PPro with their analogs.
The question is: why are you exporting an AE project to a PPro project? That feature has some use, but in most workflows, won't accomplish much. Are you intending to output your AE comp through PPro? If so, you might have Dynamic Link available (assuming you purchased the Production Premium suite or the Master Collection) which will allow you to import your AE comp as a clip into PPro. In that case, all the effects will actually remain because you're utilizing the AE effects engine through a "tunnel" of sorts. If you don't have the suite, but just PPro and AE independently, you'd probably be best served to render and export a file from AE that you can use in PPro. This effectively "cooks" the effects and modifications you made in AE; at that point, the exported movie file is just like any other. Of course, you lose some flexibility this way--whereas Dynamic Link keeps the effects "live", rendering and exporting from AE makes a flattened file that you'd need to re-render if you want to make additional changes.
Hope that helps a bit... but post back with your intentions between AE and PPro and we might be able to offer some more insight.
Yeah, I've actually "cooked" my AE projects before the link was available but I guess I'll just have to go back to doing that. Is "lossless" the best format for doing so with minimal compression/highest quality?
Building on the topic ...
... my project does not open, is because after several attempts it loads, it looks like? what do I solve this problem?
