What's the problem with the Pro/E or CFDesign6?
 

Sometimes When I open the Pro/e2001, it can not switch to cfdesign6. Sometimes it can switch to cfdesign.

I checked the Pro/e outputting file "std.out". There is fail message.

"Failed to initialize communications. Some features are disabled."

What is the problem with the Pro/E or CFDesign6? Please help me? Tks!
