Allied Assault Warchest add ons

I had Origin & had the MOH Allied Assault Warchest which I was able to play the add ons easily...now I was forced to download the new EA APP & now cannot play the installed add ons - no play button or anything!! This is very frustrating.  Why did you make people use something different, supposedly improved, when it's not improved at all.  Totally ridiculous. Also, there are no answers anywhere unless you want to jump thru hoops.   Does anyone have an answer worth a **bleep**!!!  I've uninstalled & re-installed & still nothing.  I am not a very happy EA customer right now.
