My steps are only for EA app, if you don't have the file specified at the folder I passed, you probably are not running the game under EA app, or you didn't run the repair game, a first run from EA app may be required for EA App to generate those par files

I have the same issue, even though I'm using the EA App. I've de- and reinstalled the game, repaired it and launched it but there's still no ra3_1.12.par data. Does any of you have an idea how to fix this issue?
