Mass Effect 2
Thing is you have to do this MANUALLY. Origin will not keep this game up to date for you so if you've just installed and are wondering why the game is constantly crashing open up the config utility and check your version.
If it's 1.00 you need to goto:
Download the patch and install it, one finished the Steam trainer should work.
I know this shouldn't need its own forum topic, but I think a lot of people (myself included) just assume that when they download and install the game from steam/origin/wherever it will be the latest version so they don't even bother to check.
