We had the same issue. It turns out that we did not apply the "Mandatory LabView update". It is really a mandatory update regardless because it contains the 2010 image for the cRio. Since we were using WindRiver/C/C++, we figured this did not apply to us and I think thats what might have happened to you also. Anyway, here is the link to the update:
