Opening crashing after installing Matrox TH2GO PowerDesk

Here's a problem I've not seen in any forum. I hope someone else has run into this and has a solution. After installing the current version of Matrox PowerDesk for the TH2GO digital the opening screen, not the splash screen, in FSX crashes. When the opening screen comes up, if I click on any button, like change aircraft, change time of day, change airport, etc. FSX crashes.The latest firmware, current video drivers are all installed. I'm using 3 24" widesceen monitors. All the other problems that I've seen in the forums I've had too and thanks to those of you these have been solved except this one. If anyone has any idea what could be causing this and hopefully has a solution, I would appreciate it. Thanks,Gerry
