10.7.3 incompatibility?

[katlemons]

Sorry All! I still need some help!

I'm very new to using a DisplayLink product. 5 days ago I got my new macbook set up in a hengedock and connecting through a USB to HDMI adapter. Worked great. I've never set up any rotation. I was using the HDMI display as my "main display" since the macbook was closed and in the dock.

Now all I get is "no signal" on my display when I connect it through the USB adapter. I've booted in safe mode (at least I think it's safe mode all though it doesn't say). Ive opened up system pref/displays. There is nothing there to change.... No place to "restore defaults" so then I just close display preferences and reboot into normal mode, but I still get "No signal".

Anybody have any ideas? I'm a teacher and EVERYTHING i use in class everyday is connected to the dock, so If I don't have a display, I can use any of my other technology.

THANKS for any suggestions....
