...to solve this? Yahoo Messenger stopped working properly, without a clear reason as I didn't change anything on my Blackberry.
When starting up, I see my contacts being online or offline, I can start to chat BUT my contacts do NOT receive my messages at all. The messages they write to me, come in and I can read them, BUT when I answer them, they don't get anything in at all. I am having the same problem with al my contacts.
I uninstall en re-installed Yahoo Messenger several times already and the problems stays the same.

The problem has to be at my side, as my contacts do chat with other people, without having a problem.

Anyone experienced the same and more important knows how to solve this???
