Anyone else having this problem?

For some reason when i try to launch a game on Steam, the "Launching your game" message pops up but that's all that happens, and this is for most of my games. How can I fix this?

Try restarting steam, if that fails, restart your computer. I had a problem where the "launching game" message came up, then steam would just crash and close after a couple of minutes. And I found no way to fix it besides restarting my computer. Annoying as hell.
