I cannot use the PFM nor Mod Manager. always gives me an error 0x0000007b or something like that...sp perhaps a usersript.txt file will do?

how do i enter values in a usercript.txt file? is this the same procedure as in shogun 2?

planning to go win 7 pro 64bit but here is my here is my system,
xp pro sp3, 2gb ram
gtx 650ti boost 2gb
RTW2, patch 2

please help me as i do not know if the mods i put into the ...\..\data\ are working. i know some graphic mods are working though when i test in custom battle..does that mean ALL the mods i put into the \data directory also are working?
thank you in advance
