Cannot Connect Via ActiveSync Passthrough

[Guest zenmaster]

I've broken my Lobster!

I have installed Fizz Traveller and was previously able to update via ActiveSync (USB) on both my Desktop (v 4.2) and my laptop (v 4.5). I then installed Avantgo and Fizz Traveller would no longer update, even when I removed Avantgo. IE will not connect either.

Avantgo was able to update with no problem.

I compared my phone settings with a brand new, just out of the box, phone and they were identical However, the new phone would not connect IE either.

I have run with both firewall and AV software disabled but it made no difference.

Any suggestions gratefully received.

Thanks.
