I have Workstation which hsd SampleTank 2.5 and when I loaded BIAB it put in another version of SampleTank 2.5. Initially when I tried to load the HiQ sounds BIAB couldn't find it because ST wasn't where it expected it to be and I got an error message. I then repointed BIAB to the correct location. Then when I tried loading the HiQ sounds it acted like it loaded them but I got no sound. I just tried loading a 12 string sound on the first guitar and when I checked in BIAB this should be on channel 6. So I manually loaded the 12 string sound on channel 12 and I get no sound. This was working before I upgraded to the MegaPak so I am pretty sure it some sort of configuration error,
