I want to connect my eMac to dialup internet due to the Ethernet port being busted and not having an airport card. However whenever I try opening the remote access or dial up control panel, I get this error which states that it requires the system extension opentpt remote access but it was not found. However it was clearly installed in the extensions folder. I then uninstalled it then reinstalled it but I still ended up with the same error again and again. Can someone please tell me what's going on?
