I had upgraded my computer from windows xp to windows vista.. And now WMDC is not working. I bought a AT&T 8525 with wm 6.0. First after installation I restarted the sytsem. Then tired to load the application. The application does not work at all. My mobile is too connected with the system. What is the reason. I had installed proper drivers for my system. Then any the application started but I cannot sync with the system. I manage to copy a single file but it is disconnecting in between every time. Help me to sort this issue out.
