❓ -help- with a mod

so a couple of hours ago i think, the m417 combat came out. i modded my m416 to look like it (changed the pv_m_ar and pv_t_ar) and now everytime im about to go ingame vista automatically says 'combat arms has stopped working'
anybody found a fix for this or tryed it yet?
ps.i modded my regular m416 to the m417 before

are you sure you did it right?

run as admin?, im using vista and all my mods work fine
