Widgets not working

Running latest HOG4PC software with Lenovo thinkcentre E93z, win 7 prof, on Hog3 wings with two widgets. One is former Hog2 upgraded to 3 and one is Hog3. At startup they suddenly don't work... You can see they exist in network settings but you cant "flash" them and only bottom LED is lit. Workaround- uninstalled USB drivers and reinstalled widgets- everything is working again for a week and now it happened again! Any ideas please? Computer is brand new and dedicated for the Hog software.
