Port.Open() not working for me either

"I'm having trouble getting UsbPacket to open. I'm using C#. I get a message in the debugger that information about the containing class is not available. The demos seem to run ok, though sometimes they fail. Is it possible that if the program exits during debug before closing the port that the system will need a restart to recover the use of the port? Also, is a call to Open necessary, since it is missing in the example code? Thanks." Im having this exact problem, however, there was no solution posted on the question... Mine works sometimes, but stops working after a few seconds, plus i'm getting a huge delay on reading the analogins whenever it does (infrequently) work. Help!
