I'm having a problem with FSUIPC operating in FS9. I'm using version 3.85 along with version 9.1 of flight sim. Also using Windows Vista 64 bit operating system. When I attempt to open the FSUIPC window within the flight sim environment, my screen goes blank. I can get back into flight sim using the ESC key, but cannot access the FSUIPC menu. I have tried with a fresh download of the program as well as deleting the ini file from the modules folder, but I get the same results. I've purchased the program but can't register it or make any selections from the FSUIPC menu. I've got other addons that do work (PMDG 737ng). I recently installed PSS Dash-8 & Ready For Pushback 747-200 to the system. One of them did install an earlier version of FSUIPC but I replaced it with version 3.85.
Hope you can help.
