Mmmmm.....there seems to be three types of drivers then.

QHY, ASCOM and TVDE. The ones I wanted to use are TVDE, which are definately not ASCOM.

I did a manual search of my machine and pulled out all the QHY related files that were not specific to Neb2 or MaxIm(both of which have a driver recognition file of sorts, don't know how else to put it). The tool to remove all the old drivers does not remove the ASCOM drivers it seems, for me, anyway. I then installed the set of Tom's drivers I wanted to use and now it is working fine.

I did notice that if gain and offset are not presented in Neb2, click on the advance button in the camera selection section and when that applet pops up, click the settings tab, I think it was called, and they should be there.
Thanks for the help!
