stem game probelms help

[klepto]

ok so every time i try and launch a game like tf2 it says "validating steam files" then closes every time i try and launch.. any ideas?

Try this.

Open steam and go to > My Games > Right click on TF2 > Properties > Local Files > Verify Intergrity of Game Cache

This will check to make sure that all of the TF2 files are usable and not corrupted.

If the above doesn't work try to defrag your files.

Did this just start within the last 24 hours? I think a security update in Windows has hurt Steam some how...
