Steam – How to do if steam fails to launch a game

steam

I've installed a few games everything worked flawless. After a while I couldn't any longer start Metro 2033. A message popup appears saying that Metro 2033 is launched the popup disappears and the game is NOT started.

What I've already tried:

  1. Reboot
  2. Reinstall the game -> Still having this issue.
  3. Activate the game again -> Message: User already owns this product.
  4. Checked the logfiles -> No hint about a crash or error messages.
  5. Steam Won't Launch – CMultifieldBlob(pSerialized)
  6. Opened a ticket on the steam support site -> No response yet.

Does anyone have an idea how I could solve this issue?

What if more games become defective?

EDIT:

Now I see messages like this in C:\Program Files (x86)\Steam\debug.log

[0119/095917:ERROR:backend_impl.cc(2123)] Corrupt Index file
[0119/095917:ERROR:cache_util_win.cc(48)] Unable to move the cache: 5

  1. Verified integrity of game cache

This appears to be a Steam problem, backup your data and reinstall Steam.
