Hi Madredchris,
Due to some reason the file noted is missing. It takes care for the appearance of V-Ray specific items in the 3ds Max menus. I guess the error will not appear anymore with the current installation.
Probably a re-install will fix the problem.
But before the re-install there is a file with a path like this: “C:\Program Files\Chaos Group\V-Ray\3dsmax 2011 for x64\uninstall\install.log”. If you could send it to vlado@chaosgroup.com, maybe it would provide us with futher info on that error.
