How do you insert a waypoint into the FMS/CDU for the Classic Liners Vol 2 L1011? I know the lat/long point of it but don't know how to insert that?

Nick,The only way to get waypoints into the INS is to modify your flight plan in the text flight plan.As far as I know it's not possible to add a way point manually while in flight directly into the INS, it's a limitation of the INS.ED

It is possible!Go to NAV page, then CHG RTE and INSERT WPT.Then u can enter LAT/LONG.That's all I know, haven't tried it yet ;)
