Yes, I am currently using the UIRT plugin for girder. I would frist try to reinstall the drivers for the UIRT.... I've had to reinstall them a couple of times now and again for various reasons. Also, try going into the plugins section of girder and uncheck, then recheck, the UIRT plugin. Sometimes it will come up in Red, then go back to normal after an uncheck/recheck. Hope that helps!
