Help! Renaming Glitch

Before all those Warrock fucking updates, renaming glitch used to be so simple. But now, being that im a complete fucking noob, idont know a shit on how to use anymore. It gives me all these abnomal map pack error, and i rename them back, and open the altenating folder, but it doesn't load on the map i want to. It would be so helpful in FFA. Help!
