I'm trying for hours to re-install the 2.7.5. version!!
I delete all the 3.0 features and re-installed the 2.7.5. ones, but I can't understand why it keeps displaying me into the screen of the keyboard the 3.0 version, even if I put the 2.7.5. dll files back into the pc!
Moreover..now my pc can't detect anymore the Virus usb link!!!
So now: no Virus playing, no virus as "midi keyboard" playing" !!
