Premiere 2018 can't export film because of AE dynamic link?

Hello,

I have a project with a dynamic link in it to after effects for a transition, nothing fancy, but when I try to export the movie the export stops when it reaches the AE compostion with this message:

Error compiling movie.

Accelerated Renderer Error

Unable to produce frame.

Writing to exporter: H.264

Writing to file: /User/V/Desktop/AW LIVE.mp4

Writing file type: H264

Around timecode: 00;00;23;07

Redering at offset 22,500 seconds

Component: H.264 of type Exporter

Selector: 9

Error code: -1609629695

I have had this workflow many times before and there has never been a problem. This came up just after the update. How can I do to fix this problem, why can't Premiere produce the frame. Tried to open the project in the older version of premiere but since it's created in the new version it's not backwards compatible.

It works fine to export the movie when i take away the AE composition. Please help, I need to get this video out to my client.

Thanks in advance
