Finally got all the gear to set up Sky and Freeview but W7 MCE is giving me a headache.

When I do the Prepare for Set-top Box Setup and complete it, it goes back to Prepare for Set-top Box Setup again! I can't finish it.
If I cancel I lose everything. If I do this setup a third time in a row MCE crashes and the TV card locks up. I have to reboot the htpc.

I am using an HVR2200.

Thanks.

Edit: This is all I can google at the moment. But it's not too helpful ;)
