So I have about 20 clips that I've converted using Raylight to their "green" (high quality, DirectX) codec.  I then went through each clip in Vegas and did some cropping and sound adjustments, and saved a .veg for each file.
That was yesterday.  Today I come in a click on a .veg and it shows the "Check your raylight installation" error message on the video track.  Now I can close Vegas, and relaunch it, and immediately click on the same .veg, and it loads fine.  But as soon as I close that .veg and try and load another, I get the error message.  So I have to close Vegas between opening each project.
My machine is Vista 64, but I'm running the 32-bit Vegas 8c.
Anyone else seeing this?  Anyone figured out a better way of working around the problem?  Or even better, a fix?  Much thanks!
