To explain more thoroughly. I start up the GECK, go to the File Menu, then select Data. I then double click the little square next to FalloutNV.esm so there is an X in it and click OK. I'm fairly certain this is supposed to cause my system to lag and files to load like crazy. Instead, nothing happens and nothing new appears in the GECKs windows. I must be missing something here. Any help would be greatly appreciated.
