No network, unable to display live data - UK?

All day today I have been getting this message. Is there a problem with the waze nertwork/servers or do you think it is a problem with the client?

I have full signal on my phone (HTC Desire - Android 2.1) Waze version 1.7.2.12

Thanks

Solved it!

Stupidly although I had full signal, the data connection was turned off :oops:
