BBM Connection Error: No Connection Found! after Installing BBM App

If you have problems connecting your BBM app to the servers and get an error like ‘Unable to Complete Setup’ with the error ‘No Connection Found’. It says ‘Your connection to the wireless network is turned off. Restore your connection and try again.” Don’t worry this is a temporary issues and the only solution is patience.
The problem could be due to high traffic. Just ignore this and leave it for a while for BBM to recover. Many people also get errors like “temporary server error has occurred”. All this issues are caused by servers being overrun. BlackBerry said that “6 million people signed up for information on BBM.com”.
