I'm pretty sure I didn't change any settings in my computer. I do change some settings sometimes, but I know how to put them back, like internet proxies, because I also bring my laptop to school and there's a proxy setting needed there. I've already checked YM's settings, and IE's settings, and Google Chrome's settings, and they're all set at default. So I don't think that's a problem.
The version I was using was YM8, and i tried installing YM9, but it made no difference. I can sign into Yahoo!'s webmessenger though, so I also know it's not a problem with my accounts. I really don't know what else to do. Please help me. Thank you!
Oh and btw, my laptop is a HP Pavilion tx2000. It runs on Windows Vista 64-bit.
EDIT: i also tried turning my laptop off and back on, and then tried cleaning registry using registry clean expert.. still no change..
