We have massive problems with the cache/bundle updates on our machines.
The Agent version is

For example:
DELL Optiplex 9010 with Windows 7 SP1 x64
ZCM Agent
Bundles won't update if something new has been added or updated to new version.

Workaround right now is to logout trough the zcm agent and login again. Cache/Bundles are being updated but only as long as the pc is not shut down or restarted, after reboot the agent fails again to update the bundles.
Is there fix for this? I didn't find anything on the knowledgebase so far.
