My brother just got a Canon EOS 50D and when we got home we tested the unit. He used my 450D kit lens since he bought a "body only" unit.
After taking a few shots, an error message prompted on the screen, it was
ERROR 99!

After doing the troubleshooting recommended on the owner's manual, I did a little research on the net but it seem this king of error is a "catch-all" kind of error the causes of which may involved the CF card to the Lens and the camera shutter and so on...
Has anybody here experienced this especially on a brand new cam?
Please help! Its a Sunday tom and Monday is a holiday so the Canon Service Center will not be open until Tuesday.
