I just installed iAtkos V7 (10.5.7) and ProTools 7.4.2 (also tried Vers 8) and am getting immediate dae errors (-9131 -9060) with my Mbox 2. I can't play a file from the timeline. Any ideas?

Figured it out. ProTools/Mac has to be on a drive that has only HFS+ partitions. My drive had both NTFS partitions and HFS. Even though ProTools Workspace validates the HFS partition for audio - it won't work if it sees NTFS hanging around.
