Today I was updating my Profilux 4 firmwar to V1.1.18. I backedup my prior version and began the download process. It was takinga longer than usual for the downlaod, I waited about 15 minuts and it was not responding. I cancelled the update process and tried it agian but my Profilux is not responding now, I unpluged profilux and plugged it back aging and noting is happening. The only thing I see is the small GHL loog is litup in the front pannel. Please help
