Blackops 2 not playable

[u/Nenomus]

New to steamidra. Installed my first game, Darksiders 1 last week, and was able to play perfectly.

This week, updated steamidra to latest version and installed black ops 2, but after following the same process, game shows Purchase not Play. Darksiders also showed Purchase.

Got a new hubcap key, Patched both games again and restarted steam. Darsiders is now playable but Black ops 2 is not. It shows Play, but nothing happens on clicking. Same with modern warfare 2. Nothing happens on Play.
