Hello, I have been using ichat (g'talk) since more than 3 months on my MacBook OsX. All those times i wasn't having a single problem to login and chat, and it would remain connected for however long i wanted. But recently, since this week started, suddenly it's starting to give problems. Moment i log online, hardly 30 seconds later after logging, it gets disconnected unexpectedly. The warning comes "Unexpected hangup". I checked my internet connection and checked everything, nothing seems to be wrong. All my programs work normally online. I am unable to stay connected for more than 30 seconds to 1 minute. Can you help me out with this please? I really need to use my ichat. And if possible, can you teach me how to use the Video chat also? Thank you very much. Hope to get a response to my help soon. Thank you.
