Will not trigger a build


I have just installed Automaton for the first time and have installed it on our TFS server using both the TFSSERVICE account as well as my network account that is a member of the administrations group on the server. When I check in a file to trigger a build the following errors are posted to the eventviewer and a build is not trigger. Could you please help me in getting this setup so it will work on our server?
First Error:

Second Error:
