I have had this problem on more than one system now, on every version of AE since Pro Import became an added feature. I am currently trying this on Yosemite, on a 17" Macbook Pro from early 2011.
I have called in about this problem before twice, and troubleshooted for 60min+ with the AE representative. They told me they were going to try a couple more things and contact me back. This has happened twice with no callback. I have no one to follow-up with at Adobe since ! it is a call-back-to-user system.
Is there any adobe staff (or online users) that can help me with this error.
What exact version of After Effects? What operating system?
If you upload the project that causes this problem to a file-sharing service, I'll take a crack at importing it and see what happens.
The operating system is OS X (Yosemite). The current versions I am working
with are AE CC 15 & 15.
Have you updated Yosemite to 10.10.4?
