3ds Max :: 2012 Crashes On Exit

When working on an animation project our company has faced a strange problem. When switching from one network task to another 3dsmax is closed with an error, as shown in the screenshot. Since there are a lot of tasks, a number of such messages grows frightening.

Trying to get outside of a problem, we have tried all the combinations that came about. Backburner 2008 and 2012, 3dsmax 2012 with the service pack and without it, different versions of Vray, various workstations with Windows 7 and Windows 7 SP1, to no avail. As it turned out, the problem is not in the network rendering, but in the file itself.

There were no problems noticed when working with the file, but when one closes 3dsmax, there’s an error message again. Even if we clear the scene from objects, materials, and settings completely - the error remains. But most of all we were surprised by the fact that the saved cleared scene weights 86016 bytes, but an absolutely empty scene, saved right after the program was opened, takes 73729 bytes.
