Expansion Manager 2.5 wave problem.

Hello, I own TYROS 5 and Expansion Manager 2.5 wave problem.
Can not import (load) own wav voice. The program will not let me. Where is the problem?
The same program on another PC works. That's not mine. I have WINDOWS 7 Ultimate 64 bit. of course, a legal full-fledged version.
I suspect windows updates. Alebo
Or is there any other way to put my own wav samples into the bank?

I'm attaching pictures with a problem:
