Vconfig error & error preventing Hammer from launching.

Any ideas why?

I’ve recently moved all my games from C: to X:, which is a new partition and not a whole new drive.

Things I tried
1.) Verify tool cache.
2.) Downloading the tools again.
3.) Re-downloading L4D one & two.
4.) Verifying L4D1&2 game cache.

Any help much appreciated.

you may have to run each game so it can create the gameinfo file.
