After I reinstalled SWBF2 and patched to 1.1 using the international patch it did that bug when the game wont run saying the disk is wrong, this isn't a new problem but I cant remember how to get passed it.

Is your swbf2 on DVD or CD?

IF you have the DVD version try this

This is a known problem with the DVD version and some DVD drives.
check this link
Securom FAQ
It lists the things to do if you get the errors.

Basically you run the analysis program they link to, send the resulting file to them they in turn send you a version of the swbattlefrontii.exe file to put in the directory and then your game will run fine in 1.1 version. I had to do the same thing for my DVD version/drive combination.

this bug i had, too.
Darth_spiderpig tolt me to put this in the gamedata folder.

A question about this: is it posible that if an other person using 1.0 and using 1.1 can not play lan together?? because i couldn't see the game??

edit: i reinstalled swbf2 and than only put the exe in the gamedata folder and it worked. the international... i don't need.
and than i installed the unoffical 1.3 patch
