Problem with craetion of planes in a part

Hello.

I am using SW2010 on a computer with Vista.

Everytime I try to make a new plane, it crashes.

I already tryed to repair it and uninstall/install few times with no results.

Technical support was as helpful as a finger in your eye.

A friend of mine suggested can be a problem with an update of windows,

but it is impossible find out which one.

Does anyone have some suggestion ????

Thank you
