Stopped Working??

After several weeks of working great, today I noticed that UltraGCIR3 was not showing up in the manage plug-ins. Sure enough, the IR was not working. I restarted HS3 and then the PC, and each time noticed it was not looking for (or not finding) my 2 global cache devices.

I have HS2 and HS3 on the same computer, so I disabled it on HS3 and enabled the HS2 version and it finds my devices and works fine. Suggestions?

Thanks
Gary
