Celibrye: Hello, this is celibryes friend, her english is terrible.
But so the problem is that the game crashes if mouse is clicked in certain levels. If keyboard is used, there is no problem.
Okay, that is indeed a strange problem. One which while I'd like to diagnose it, I cannot, as the program has been entirely stable for my entire usage. So we should go ahead and contact support as seen in the top menu.
There should be a utility included with it to generate a spec report for her computer, or the DirectX Diagnostic program would print an acceptable report as well (DXdiag.exe or localized equivalent.)
