Rez Mods "Not Found"!

Hey everyone! I'd like some help on resolving this problem dealing with my Rez mods "not found" as a status when adding to the RezInjector. The status resulted in the Rez mod injecting as a failure and the game will not run. I've successfully modded a g36 -> g36 Valkrie because the status for the mod was "ok". I've looked around for forums that are similar to my problem but I can't seem to find one! I'll list the mods i'm trying to inject:

***Alex's L96A1 Arctic Fox Mod***

PV_SR_DF_L96A1ARCTICWOLF_BC.dtx
PV_SR_DF_L96A1ARCTICWOLFCAMO_BC.DTX
PV_SR_DF_L96A1ARCTICWOLFSIRENSERCAMO_BC.DTX

all into GUNS_T_PV_AR.rez

Please help!
