Is there a <config-version>2</config-version> in the minion.xml? Minion now utf8->base64's the path since many users had non english characters in their windows user name causing the xml to fail validation.
Yeah there does seem to be a problem with this with the version that is live. Looking into it.
Until this is fixed you can use the Add Game button at the bottom of the game list. Add a new ESO game and choose the liveeu path. Then once that is done delete the one with the live path. Do not delete the current game first, do that after you add the 2nd game.
