Hi Brownie, that error comes from using an old v3 beta release (like a cracked version) which is missing some functions that are in the v3 final release version.

So to fix that make sure you're running the release version of v3 and not a cracked version. If you purchased MoI you can get a new download of the full version installer by putting in your license key at http://moi3d.com/reinstall.htm .
