Black Ops did not opening. No error messages

My Black Ops not working after update (I have russian CD-Key) On my laptop it did works well but on my desktop It is not the same, It didn't even try to launch it .. When I look to running applications I can't see BlackOpsMP.exe. I already defragment the game.

Try reinstalling the game

I did now game close itself in about 10 seconds with the error which came with this new update '' Exceeded limit of 256 'stringtable' assest ''

Open your Library and right-click on the game and click 'Properties'. Then click 'Local Files' and choose 'Verify integrity of game cache'.
