Matrox Triplehead2go DP - only registering 1 monitor

Hey peeps,

I am trying to get my triplehead2go running 2 projectors via thunderbolt from my MacBook Pro. I have had this working in a different computer, but when I try on this one, the software only detects 1 monitor, even though I am getting images from both. I am using this for running custom projections, and don't need it to mirror. Any ideas as to why this is happening? I have tested mutiple cables and adaptors, so I do t think that is the problem.
