My CSGO and TF2 is not working Please help!!!

That would be nice if you told us what you tried already, since you said it's not working.

Have you tried clicking "Play" ?

how is this a bug of SG mate? :/

Probably be better to ask on their forums which have I presume tech support sections?

That said, off the top of my head. Using Steam Client Beta?

I have try verify integrity of game cache. and try google the the issues and look at random videos trying to fix the issues and look at steam forms and Swagalicious I have click the play button and yes i am using steam client beta

Have you tried rebooting?

If not, a burnt offering to Gaben might do the trick. I recommend a fresh sparrow, but if you can't find that, a torched Big Mac is widely considered to be an acceptable alternative.

If you've tried everything else, you could try reinstalling Steam over the top of your current installation. That's a desperation measure, and make sure to back up (i.e. make a copy of) your Steam folder, first, but it might clear up the problem.

Also, as has been suggested, you should probably be asking in the Steam forums rather than here.
