BB Bold 9700 :: Yahoo Messenger?

I have a 9700 eith the latest version of the software installed.

I read an article on the net that said to free-up device memory I should install items to my memory card.

In Application World, I highlighted Yahoo Messenger 2.5.32, clicked archive & it came up archiving complete. I tried to use the app but couldn't so I restored it, restarted, typed in my username/password & my contacts no longer received any of my messages.

I read on the net to remove the batter & try again, which worked until I logged out of Yahoo & since then Yahoo hasn't worked since. I have removed/re-installed it a number of times, removed the battery & nothing

Before I clicked archive & if logged on to the computer then logged on Yahoo with my 9700 it said on the computer I have logged in from a different location. If I was logged in on my phone then logged in via the computer I used to get an error 100 (unable to connect to the server) meaning I was logged in from a different location. Now, I can be on the computer, login on the phone which doesn't log me out of the computer & I can send messages from the phone yet no contact receives them. Go to the computer & send them with computer & phone logged it & automatically the contacts get my messages.

Also, if I remove the application, auto-restart when the phone comes back up I see a 'Y' on the Yahoo e-mail folder, but not always.
