I can't seem to utilized my cf codec that came with vegas 6. I tried uninstalling the trial version but no luck. How do I get my supplied cf codec to work again?

Delete CFHD.dll from window/system32 then you will revert to the old Sony license codec. Normally this is removed by the uninstall, yet there is an option to leave the codec installed (which you may have accidentally selected.)

Doesn't work .

Then you may have Sony Vegas install issue, as we not install the VFW codec anywhere else. Try re-installing Vegas. This all very odd. What version of Connect did you try?

V2.1 version. Will my current projects be affected when I reinstall Vegas?

Thanks

They shouldn't be, yet you shouldn't have had any license issues either.
