Hmmm, something like this happened with me too. Except, there were no problems with anything in max (Except trying to open previously saved files). Well, one thing you can try to do is, restart your computer. If that doesn't work, try testing 3dsmax by making something really fast, save it, and try to reopen it. If it opens up, then everything should be fine. Another thing you could try is saving it as a .3ds file and importing it or just make two files of the same thing in case something like this does happen. Anything other than the things I've listed here, I don't know what to do. Hope this helped.

P.S. Try to uninstall the mouse software too and retry it.
