EA App is a total disaster

Ok, so a little bit of an uncommon game but I hope I'm not the only one stuck with this problem. EA forced me to uninstall Origin and switch to EA App and I wanted to play Medal of Honor: Airborne that I've bought via Origin. And the same thing goes everytime:

• I install the app
• I download the game
• The launcher says the files are corrupted
• I run a repair
• I never ends and gets bugged
• I clear cache / reinstall the app / run a recovery
• The game is magically gone despite having files
• I need to install it again (aand repeat)

Clearing cache from Origin or EA App, running as administrator, all basic solutions don't help, I tried to do multiple things from various tutorials and reading a lot of threads and I can't get this damn app to work. I never used any mods or "tricks" with these since I never really bothered, but now I'm mad.
