Would it be easier to just downgrade my mod?

Hey guys um, my friends and I are trying to get a little session mod going for us but we keep having an issue with the flserver crashing around the Kusari territory. It will let us play for… about 30mins or so, maybe longer or shorter but whenever we are in that area it just explodes and craps it self. There is also some issue with a few plug ins but it doesn’t seem important (the bank plugin and stuff like that). We really like this mod and the balance it brings to the game so if anyone has any ideas, please help. Thanks

Oh we are running on a 64 vista ultimate os
