I was asked to describe this here.
Today i lost some work when After effects crashed.
Project wasn't intense and i dragged something out of my library into the composition.
When i released my mouse it gave me an error message that i didn't read. (pressed OK without reading like always)
A second one popped up, which i read and was confused by.. :
Not sure what happened, and can't seem to find the crash log either.
Sorry for your issue!
Which version of After Effects are you working in?
Are you able to replicate this error in other projects/comps?
HAH! That probably shouldn't have slipped in there. I wonder if anyone at Adobe has seen this thread yet.
