Nikon-Sigma live view focus problem

[RobSaecker]

I recently picked up a used Sigma 150 Macro, and it will not focus in live view on my D7000. This isn't a major problem, as I usually use live view for manual focusing, and I doubt I'll ever use this lens for video, but it seems a little strange. It's pretty much dead on in regular AF, and none of my other AF lenses have any issues in live view. Anyone else have similar experience?

I don't have any problem in Liveview auto-focusing with a D7000 and a Sigma 30 F1.4 HSM (needed finte-tuning) nor with D800 and Sigma 24-70 F2.8 HSM.
