It's crashing to me. Are you using it on a virtual machine?
And I don't think you can change the location anymore as it only says virtual location 'USA' only...
Nah, I'm using the physical OS. Well, we never could change the location. When I connected it showed either Virginia or California. (To switch between them just connect-disconnect several times) With Virginia I wouldn't qualify because it will "problem contacting the offer provider", so only California worked for me.
Now it only shows Virginia even though I connect-disconnect many many times. So no more offers for me :P
What states does Spotflux gives you? I might help you depending on the location.
