I hoped to get you part of the way there, but no luck. Mylenium -- a very frequent contributor here -- used to maintain a list of AE error messages on his web site, Mylenium.de. Perhaps he still does, but I couldn't find it. I might be blind.
Since it's after 10 PM in Germany right now, a reply may have to wait until the morning.

No, it's gone (and I'm not gonna explain the million reasons, in case you wonder; sorry).
Does anyone have any idea what this error message means and how it can be fixed?
We need more info. This error is usually coming either from a bad source footage file (damaged, quirky CoDec etc.), a leaking effect that has problems with its internal math or some other stuff that may involve certain calculations like 3D layers, text and what have you...
