Problem setting up eyefinity with 5870 Crossfire

Setup:

3 24" (DVI, DVI, Display Port to DVI converter)
2 HD5870
W7 Pro x64
Cat 10.10

I had this whole setup working perfectly when I got it about 6 months ago. Shortly after I had to move and didn't have room for an eyefinity setup so I was just using a single 24". I now have a new place and the room so I pulled the other 2 monitors out of storage to get my setup going again. But now I can't seem to get it working again.

I can get it to detect the 3 monitors and extend the desktop to all three but when I try and create a group it disables one of the monitors and I can only create a 2x1 or 1x2 setup. Turning CF on or off doesn't seem to make a difference. I've also tried different combinations of connection (dvi and dvi to first card, dp to second card; dvi and dp on first card, dvi on second card) but still nothing. Any ideas before I update or roll back the drivers?
