AOL doesn't share its knowledge base and I have never used their service. You get to call them when their software fails.
The only guess I can offer is that you could have left out some details in your post such as you installed Windows recently. Remember that Microsoft doesn't fetch and install drivers for modems or much else.
Running Windows ME. When I would connect to the internet the windows would not load fully and I would get disconnected. If I did connect I could not stay connected. I restored my hard drive and reinstalled AOL with the same problem. I purchased a new modem and this one will not work at all. I have installed the driver, there are no Resource Conflicts. when I go to System Properties>Modem>It is there but has an error>"Cannot Read Port name from Registry". It is installed on Com1. I also get this error "The modem failed to respond. Make sure it is properly connected and turned on. If it is an internal modem or is connected, verify that the interrupt for the port is properly set". What do I need to do?
