I just installed 2.5 on my machine (Os X.6.
Plugin is running as expected, until you close the GUI and reopen it again!
ALL the parameters (Sliders, Knobs, etc.) have got different positions as it was before, but the sound isn't affected by this.
The problem is, that i can't tweak the sound anymore after reopening the GUI!!
Now CS80V is unusuable for me...
And i really like the sound of it!
Do you know the problem?
