Well i just picked up my new Tilt a few days ago and have not be able to try out any ROMs yet cuz activesync is crazy. I had 4.2 running just fine for the longest time with no problems. I now have the tilt and needed to upgrade to AS 4.5, so i did with the cd from the tilt and everything went fine. I restarted after install, clicked AS to open and nothing happened. I connect the tilt and the icon in task bar turns green and spins and says connected, but no AS window. I can explore the phone, go to connection settings from right clicking the icon, but i cannot get the window to open. I have google'd from here to goggleland and back and cannot get it working. I actually did get the window to open ONCE, after i completely uninstalled Kaspersky 7.0. But then after i closed it it never opened again. The one thing i noticed is that if i open the task manager on my pc wcescomm.exe and rapimgr.exe are running, but not WCESMgr.exe. When i double click the AS icon i see in task mgr that WCESMgr comes up but then disappears. Does anyone have any ideas as to what i can do??
