Hi. Similar situation to David's above. Other forum pages suggest the 2.5.1 installer might work. Would it be possible to request a legacy installer in this case? I'm not currently interested in getting a refund.
Also unable to use Precision Time Align, though Blackhole, H910, and UltraChannel are running perfectly.
Sure, email firstname.lastname@example.org and we can get you a legacy installer to try.
