For over two months now, I can't access my whatsapp on my blackberry 9800(touch1), and so implies to other users of the same phone..

This started when there was a new upgrade of whatsapp.. And after the upgrade it refused to open since then, when try opening it, it shows |error starting whatsapp:error loading module 'whatsapp' verify error.

Please is there any one who has encountered this same problem and has a solution to it?

Thanks in advance..
