Stupid Newbie Host Question

[CaptRR]

I'm hosting a proportions game on PBW. The problem that i am having is when I try to start the game using the PBW java client I get the error "Data files currently being used do not match the data files used when this game was started".

Now if I launch proportions using the mod launcher, then shut down se4 and then use the pbw utility, it starts fine.

Is this normal when playing a modon PBW? Or have I done somthing wrong in the setup.

We are using proportions 2.5.3.1 BTW.
