I have a blackberry 9300 and it won't send or receive any BBM messages for some of my contacts. When I send a message it shows the tick without a "D" or "R" over it and I can't receive messages from some of my contacts. They also can't see any updates I do like status update, display picture update, etc. My BIS is activate because I can go onto the internet and I can use Whatsapp, the problem is only with BBM. I have tried deleting and sending service books but it hasn't worked. I also deleting my contacts and re-invitign them again but that also doesn't work. My last resort was deleting BBM and downloading it again, it also didn't work.
