i know its my bad, usually i have autosaving on and dont care to much because of that.. but this time i opened an old AE7 project so it was opened as an untitled project.
however when i was done and wwanted to put my comp into the render queue i noticed that it was still unsaved so i tried to save it..
AE just flashed but nothing happened and now i cant click on anything, nothing happens when i do. the task manager doesn't say its crashed and from time to time some messages like "cant create drawing surface" or something like that pop up..
i know its probably lost but since AE is still running is there any way to recover it from some temp location or extract it from ram or save it somehow??
Nope. As you already noticed - it's gone. And the "drawing surface" bug was fixed in a patch update for CS4, so it sounds like you haven't done that, too , and should do so ASAP...
