Ichat not working! Messages won't send.
When ever I try to send a chat message to a listed buddy or a new buddy the message won't leave the type box. Ichat shows that I am available to other accounts, and when they send me messages their accounts show I recieve them even though I do not. I researched other peoples questions and answers but no matter how many times i change the numbers 5190 to 443, the original code takes place of 443. Recently, about a month or so Ichat and Safari went down but I still had internet access to google chrome. Ichat was completely lost and I had to go to the Snow leopard DVD to get Ichat back. Did this have anything to do with Ichat not working now? Please help me for Ichat helps me connect to my family far away from me. Thank you and please respond.
