Discussion: Freezing on Today Screen.

Freezing on Today Screen. Today I updated my 6800 to the newest version of Windows Mobile, I turn it on and it freezes at the today screen. I take out the battery and try again, same thing. Then, I try to reinstall the software later that day and nothing happens, the computer canot see the device since it locks up when it start. I try restarting the device while it is connected to the computer. It connects but then eventually drops.
What can I do?
