I have an ADS pyro link that I use for external monitor preview. It used to work fine but has mysteriously stopped working. I can still preview from the explorer or trimmer pane but not from the project itself. The preview window doesn't even work when I disable external preview!

I have tried to load older projects and they have the exact same problem. The only two things that have changed in my system recently would be enabling "generate midi time code" and upgrading to Sonar 5.

Not sure if either of these could be a problem but I am stumped. Not thinking it's a hardware problem.

I tried updating to 6c from 6b to fix the problem but it did not help.

Any ideas?

Thanks, wm.
