Launching Steam GAmes

[willseal]

HI,

 

I have just wiped my pc  am reinstalling everything again. I have most of Bigbox setup and have imported my games from steam. 

However when i launch a steam game it looks like it starting to load but then the big box game screen reappears and nothing happens it just plays the games steam trailer as if i hadn't launched the game. All the games launch fine in steam

Any help would be appreciated.

Can you launch a game from cmd?

e.g. "explorer steam://rungameid/24740"

If that not works, it is not due to LB, but probably to steam itself.
