After CMA update, DATS not updating

[gshand]

I am currently maintaining ePO 3.5.0.635, & have just updated CMA to 3.6.0.569. When I update the agent on PC's the DAT's will not update. The agent log states that the PC is running the latest DAT. PC is running VSE8.0i patch 13. I have been able to resolve this by uninstalling/reinstalling VScan.
Here is a copy of the agent log & McScript log.
