plist wont write on first run on other computers?

SOmeone please help. I know I have seen the answer to this in an old thread but its late, everything is blurry and I cant find the thread for the life of me.

After building my app in deployment mode and running it on other computers, the app runs fine. Its just the plist won’t write to the preferences folder and I keep getting a “NSReceiverEvaluationScriptError: 4 (1)” when I trigger any of the scripts that are supposed to write to the prefs folder. If I copy the plist file from another computer to the folder and run the app again, then there are no problems.

Please help! This has been a long week and I am soooooooo close to gettin this thing finished!
