Hi Alexander, Are the LGD queries that worked against the lod.openlinksw.com server giving a specific error when you attempt to run against your EC2 AMI with the LGD datasets loaded ? Also what is the exact version of the Virtuoso EC2 AMI, this will be reported in the left frame of the conductor UI ?
