If your AE render to sequence filed fails, just restart AE or even a hard reboot, and head on to the render queue. Select the comp name and goto the edit (or comp – can’t recall) menu and choose duplicate with filename.
You’ll get a new render item. Look into the Render Settings dialog window and you’ll notice that AE automatically changes your in point to reflect where it last saved your seq – IOW when your system crashed.
Granted, if it was a stupendous crash, then chances are that AE may not have been able to save the required data.
An alternative is to import the entire Premiere project into AE using the File>Import> menu. Just select Premiere Project and that should be a better option than copying and pasting between the two apps.
