Revit Architecture 2013 Closes immediately after splash screen

[freakyword]

Hi, this problem have been harrassing me for years, not just in Revit Architecture, but also in AutoCAD...Sometimes I fixed it somehow, and later after a couple months it showed up again.

I used Revit Architecture 2013 student version. The program disappears after it loads into the screen where it asks you to open project or create a new one. Could you help me figure out this problem? Thank you. I don't know why this problem has happened to me on each one of my laptops..

Thank you!!

Have you tried doing an clean un-install and reinstall of the software? you probably  have but need to start somewhere..

This link will explain how to do the un-install:
