"Topic!" Error after switch form AOL to Bellsouth/AOL
If you are still using the AOL browser, then that may be the problem.
How is the DSL modem connected to your system, i.e. is the DSL directly connected to the PC's NIC card. I would recommend a router, which has somewhat of a firewall, plus allows one to add other PC's to a local network (LAN).
You should be able to go through MS Internet Exlorer directly, if the modem is set up correctly, and the modem should be set up through the browser anyway.
In the IE browser (See Tools > Internet Option > Programs) to see what is set up for your email and other browser functions.
