Error: Could not find or load main class

The launcher says:
"Error: Could not find or load main class and
Game ended with bad state (exit code 1)
Deleting C:\Users\zombiehunter\AppData\Roaming\.minecraft\versions\13w23b\13w23b-natives-2570161452964"
... and stops. The game does not even start. Tried it with different snapshots, profiles and profile settings, nothing helps.
