The message reads: Unable to initialize PM Interface Libraries.
I'm using a PM5 to test with and I've had no problems getting it connected and getting my software to detected however all the CSAFE commands i have tried to send result in a USB time out error. I'm developing this application on windows using C++ and MFC. I've just started work on an application which will provide a speaking interface to the PM so that blind users are better able to use the functions.
