I have Mac OS 10.6.8 and get "An internal FaceTime error occurred".

Is there a fix in the works. Apple says click only once on icon but this is to no avail for me. Would REALLY like to use facetime on my MacBook without having to go into the root directory to modify something that should already be modified in the program's release. Does anyone have THE official answer for a fix? Is this one of those things I for which I need to call Apple and pay for the tech support to get it to work, or does it just not work on OS 10.6.8?

Any assistance would be appreciated.

Tia to all who respond and have a GREAT evening evryone!
