For some reason my download kept aborting, saying something about an invalid COD, so I just gave up on it. From past experience, I was never happy about the delays in transmission from this SMS-based system.
So I'm currently testing Verichat and it seems to be working nicely. I'm interested in only Yahoo IM so some of the other free ones (Ramble, etc) aren't an option for me.
Sorry I didn't help your issue - but FWIW...
