ok, i got my dad to allow me to install FSO on is comp, so i took me FS dir, cleaned out the mess, ripped out the zpack mvp, put all the VP's in the main folder, but the weapons pack in the enhanced folder, ripped out all the old builds, made sure everything worked, wrecked the network for half an our transfering the gigabyte of data, ran the retail launcher, ran the FSO launcher, ran the game, played. Now, my little brother wants to get slaughtered over the LAN, so i set up my PC as a LAN host, using the EXACT SAME DATA as my dads PC.
I go downstairs (dads PC), discover i am using a builld from a month ago, i switch to the right build, use the -mod param to get FSO to use the weapons pack as well, setup pilots and stuff. Enter the IP from my own PC, make sure PXO is turned of, etc, etc. I try to join the game i'm hosting on my own PC, and i get a warning
"you are running an older version of FS then the host, click the update button in the launcher to get the most recent version".
now, i am running the exact same build as upstairs, but from a different path. so i try to move the stuff to the exact same path, and try it again, same error.
My dad's PC runs winME, i run win98SE, and we are connected through two hubs connected to eachother.
known issue? if not, i'll copy&paste to mantis.
oh yes, almost forgot, when i hit escape in the server list, i saw a flash of Kazan's rathaven chat thingy before the mainhall appeared.
EDIT:
This also happens with AND without using LS's new weapon effects.
