Patch Manager - WSUS server update error

Hi Everyone,

I installed the patch manager to a different server than the WSUS server and logged in as domain admin to the server. when I run the PatchManager app and register the WSUS server it is ok as communication and credential wise. when I try to sync the update list from the WSUS server after a while I am receiving ' Column 'isubscription_lastmodifiedtime' does not belong to table updateserver. ' error. when I check the database I do not see any table named updateserver. Anyone have an idea?
