I am having an issue whenever I try to open a project in AE 2015 (22.214.171.124). I thought it was just with one project (and all of the auto saves that I tried opening of that project as well from up to a month and a half ago), but I tried to open another project and got the same exact "Warning". Any thoughts? I started having this error problem yesterday. I gave up on troubleshooting and then downloaded the latest update through CC. This is a file I use just about weekly. Its a segment graphic that I make small changes to it with a new picture at the end and re-export each time and I've never had an issue with this previously. I have tried restarting, re-installing AE, re-installing plug ins that I had switched to a previous version to work in FCP7, restarting again, etc. Still have the same problem.
So when I open the main file I've been trying to work on - SOME of the work remains, but nearly all of the pre-comps and raw video that are normally there are removed from the timeline. Like they were deleted. There is still one pre-comp that is used around 14 seconds...it seems unaffected. Any ideas?
Since I need to work on this project I have downloaded AE 2014 (126.96.36.199). It opens the project just fine and I have been able to make the adjustments necessary and exported the new file.
Here are my system specs: Mac Pro 6,1, 3.5GHz 6-Core, 64GB RAM
Nobody can tell you anything without exact info. You are losing yourself in vague descriptions. What footage? What comp settings? what effects? what else? You need to be much more specific.
