Server Certificat​e Error messages

Question

I have used my 8900 curve for over a year but in the last few days I keep getting error message come up
saying either bbm.voip.blackberry.com or rcp2.eu.blackberry.com server certificate contains different domain name then gives my Wifi BT .net address?
This keeps coming back - I have seen on forum that some people have taken phone back to version 6 of BBM and this has cured problem but I cant see where to remove BBM version 7 so I can reinstall the older version?   Is this a common problem with the BBM7 update?

The problem is not with BBM7 , if you want previous version of BBM you get it easily but Before downgrading try those steps , if it fails let us know.
