Can't use gaim with yahoo account

[Kamaraju Kusumanchi <kk288@cornell.edu>]

I am using debian testing.
Since I cannot find yahoo messenger in the debian packages, I thought of 
using gaim. But in gaim, whenever I go to accounts button and click on 
the on-line box, a window pops up and says something like this

username has been disconnected
date
unable to read

   reconnect    close

Even If I click on reconnect, nothing happens...

I am able to use hotmail account without any problem. The only problem 
is with yahoo account. Can someone tell me what I should do?

thanks
