Lol trying to do Lv X or 215 I guess. =[. Coz no other file should be screwed up because the installer doesn't lag, well thats what I think. Only the new maps added should screw up due to the high ping while updating, try shut down some background programs. Then go to your version.txt and delete all the text that had something to do with _map or just with the word map in it. If you need further help just PM me please.
