sharing aol dsl connection

Hi

My partner has an aol connection which is connected to her PC via USB. I have installed a second PC and networked it to hers via the ethernet port.

Now I want to share the aol connection with the second PC. I have set up internet connection sharing for what that was worth. It did not work and i cannot share the connection. To further compound the issue, when I closed aol and reopened it, it denied access until I disconnected the second PC from the ethernet port.

I have looked at the aol help page on this and it states I must get a router. I find this a bit hard to believe. Is there a document that tells you step-by-step how to achieve sharing of this connection? Is it possible? (in that, have you seen it accomplished)
