I downloaded and installed Excalibur 6 for my Vegas 8.0a install. It "appeared" to install fine, but when I open Vegas, clicked on View>Extensions>Excalibur>Excalibur, I get this error:

"An error occurred during the current operation. An error relating to security occurred" The only option is to click "ok".

So Excalibur isn't running at all. I've tried rebooting, and I don't know what else to do.

I will say this...we had previously upgraded this workstation to 8.0b, found that had some bugs we couldn't get around, so we uninstalled 8.0b, and reinstalled 8.0a. Could that be causing the problem somehow?

Thank you very much for any help you can give!
