I am a new owner of Arc 4 System and am experiencing problems. Basically it appears that everything is installed correctly; I have created profiles; the ARC System box shows a signal; the ARC software window and the ARC 4 plugin seem to function but... when I activate the "Correction" button there is no difference in the sound.
It all worked when I gave the trial version a run but now... nothing.
I have submitted a trouble ticket two days ago but have not had a replay yet.
