Artisteer provides a set of tests for plugin developers and our plugin passes all the tests and no errors happen on my machines using the plugin so I'm not sure why some people encounter this problem.
I know of someone else who had this problem and they contacted Artisteer for support and were provided with an updated build of Artisteer that solved the problem. I would suggest that anyone else who encounters this problem do the same thing and contact Artisteer support.
Hope that helps,
Joe
