Hi all, Please help me to fix my yahoo messenger. I could login to it but could not chat with my friends. The chat window does not appear and when i go to any chat room, the error message appeared is "chat error". I suspect this happened after i downloaded and run "Spykiller antivirus" Tried to do the following but fail to fix it. 1. Uninstalled & reinstalled yahoo messenger 2. Uninstalled and deleted all traces of Spykiller 3. Uninstalled and reinstalled internet explorer 4. Set the connection to: no proxy, firewall with no proxies, no network detection in the yahoo messenger Is there any one who can show me how to fix it. Thanks in advance for your response.
