BB Mesenger not working
 

Hi everyone sorry im new on here
i have a question and that is i have a blackburry curve and all of a sudden i can not bb my friend in the USA or anyone else there i can add here in the UK and every where else but not USA all of a sudden does anyone know what the problem can be

thank you

All of a sudden, as in just this past few minutes?

I have problems to call or accept invitations when you use only email. While others seem to have their PIN as an alias, email / PIN are interchangeable, mine seems disassociated.

I receive email invites, but not collected in the BB IM and email in the real world there is no option to accept, just a link to the download site and mobile applications a long string of seemingly random characters.
