Anybody else lost the BBM app?

My Z30 went mad yesterday afternoon and I've lost the BBM icon off the home screen and can't view or edit messages in the hub.
When I link to blackberry link on my PC it doesn't recognise that the phone is connected.

I know a couple of other ppl that had the same problem at the same sort of time yesterday!?

Anybody got any ideas whats going on? Is it a problem with Blackberry themselves?

have you tried rebooting the phone? Have you checked all the folders to find the app? What about going to BBW and downloading it again?

Country block?
