I experienced this tonight. I thought I had forgotten to update the Classmate but all indicators show that the update was previously installed.
When using the classmate, image FRC_2010_v5 was available. This is AFTER the DS Update (which is for the classmate). It formatted fine but after installing programs, we could never see the battery value nor would the program run. The symptoms you described are what we found as well.
Thus, I tried imaging from my laptop which also was updated. It had version FRC_2010_v10. One of our student caught that thankfully and said that the classmate's version was older. The cRIO imaged correctly, and we saw the battery voltage! Installed the program and it ran! 20 of us high-fived as we thought the problem was the classmate had not been updated.
However, I think the DS update has FRC_2010_v5 while the Laptop/LabVIEW update has FRC_2010_v10. I'll try and post on USFIRST as well because I think other people will hit this problem.
I hope this is/was our problem and we will format from the laptop only. It has been a set of nasty nights getting that figured out.
DS (FRC_2010_v5.zip) update came from here:

Laptop (FRC_2010_v10.zip) update came from here:
http://joule.ni.com/nidu/cds/view/p/lang/en/id/1534. Same as page 5 of the Controls #2 manuals and the US FIRST Controls web site.
Anyone else having this problem?
