During a conference I get an "Abnormal Program Termination (C++ Runtime Error)" message

This happens when the software did not have enough resources to continue the conference, usually memory, cpu usage, or network ports. Reboot your computer and only open the programs necessary to host or participate in a conference.  If the problem persists, try disabling anti-virus software and programs that use internet bandwidth such as ICQ, MSN-AOL-Yahoo Messenger, etc.
