S710 - Orange MMS - Error Synchronising?

[Guest Ponty]

I can't seem to send/receive MMS messages?

I have been through the settings with Orange over the phone and have tried the HTC setup wizard, but each time I try and send/receive I get the 'Error Synchronising" message.

I've done some searching and the only thing I came up with was to remove spaces from my numbers, which also didn't work?

Any ideas?

Many thanks
