OK, i got it fixed.
I went into the configuration utility and noticed that all the settings were deleted out of there. So after I entered in Supervisor Host, Domain and Windows Domain again, restarted the QubeGUI, it connected and all my hosts were listed.
It's just weird that this happened all of the sudden, and right after I installed 3dsmax 2010. I wonder if something that was installed along with the program cleared it out somehow. I'm curious to see if anyone else has had this same issue?
Maybe it has something to do with Microsoft Visual C++ 2008 SP1 Redistributable that gets installed with Max 2010?
