Can't launch with scripts

Hi so I purchased scripts today for dayz mod and they have exactly what I want, the problem is that I am struggling to get the game to launch I have to launch the scripts prior then launch arma 2 oa and go through the server menu. When I launch the scripts and then go to launch arma 2 oa I get "failed to start process for arma 2 operation arrowhead access is denied (0x5)". I believe I have my antivirus fully disabled when I launch it but im not sure as I feel like thats where the problem probably lies. 2 times that seem entierly random I have been able to launch the game but if I close it and try again I go on a streak of error messages. Does anyone have a solution for this problem.
