X6 crashes on opening any and all files

Hi, I am a brand new user of X6, I had previously been using X3 which has been wonderfully stable. So far I really like X6 accept for one issue:

When I open a file the program crashes. It doesn't matter what file, they all cause the program to crash. It seems that X6 just cannot create the work environment unless it starts from scratch.

The solution I have found is to start a new document first and THEN open the file I want.  After that, everything is fine. I can open any files I want all day with no crashes. Kind of weird, but what the heck..at least it works. By the way, my files are typically small (less than 2MB) composed of a few jpegs, some text, and some simple vector shapes.

I am using the 64 bit version of X6 on a 64 bit pc running Windows professional with 8GB ram.
