Changed sim in my blackberry curve 9320 and the email has stopped working - it keeps saying it can't connect to the server even though everything else is working?

Try turning off your phone. Then remove battery. turn it back and turn it on. That does the trick most of the time. Dont forget to rate me. Thanks

The setting should be on your phone. Either delete the account on your phone and reset it up. Or check the email settings option.

see the solution on 1) http://helpdeskgeek.com/how-to/microsoft-register-server-has-stopped-working/

OR
2)The Register server is a program that tries to register .dlls and activeX controls. Is there any other file mentioned when you see this message?

Have you tried uninstalling and reinstalling?

you may need to have the OS reflash back into teh phone you can take it to your mobile carrier and have it done there.
