i know it asks for a .blend file but if you try it on a new screen that has just the cube and hit the add button it instantly crashes for me. im on windows 7 64bit and using the 64bit version of blender. i also have it on my mac but it doesnt crash for me it coudl be the mac version is 32bit granted i might be running the 64bit kernel. right now i am not home to include any information from the windows logs but will do it later on today in the hopes it will get this bug resolved. is anyone else experienceing this.

i have 2.5 a2 from graphicall.org will try a newer build and update the bug.
