Game needs admin permissions

This game used to run great, now, I have been trying to get it to run for days to no avail. I have uninstalled and reinstalled, followed all the suggestions in discussions on the subject, but nothing works. Every time I try to start the game, it gives me the pop up that it needs admin permissions. I have chosen run as administrator for the game, EA App, and Frosty Mod Manager....no matter which way I try to start the game, I get the same pop up. I have almost thrown my computer several times because of this....can anyone help??
