After I choose which files for the geck to load, it doesn't load anything. I've used the geck for fallout 3 and the construction sets for morrowind and oblivion, so I'm familiar with how this should work. I downloaded the new vegas version from the official site and installed it into my fallout nv directory. From looking at the open files window I can tell that it's correctly finding the right data files. It doesn't matter which files I have marked to load, clicking the OK button closes that window but nothing else happens. Reopening that window shows that falloutNV.esm has been unselected but the other files still are.

I'm using the ultimate edition of fallout new vegas, and geck (new vegas edition) version 1.1.0.262 and 64-bit vista
