Internet Dialer: PPP not Installed Message

When I launch the Internet Dialer I get a message that PPP is not installed or is not active. I have reinstalled Apple Internet Connection Kit and the problem persists. All PPP components appear to be installed correctly. What is causing this?
This issue is caused by the an extension named AOL Link. To remedy this issue:

1) Launch the America Online application. Choose Preferences from the Members menu, and scroll down through the list and
click once on AOL Link. Deselect the Auto Configuration checkbox. Quit America Online. (This is important to let the AOL
application work properly.)

2) Disable AOL Link in the Extensions Manager.
