Why won't ROBLOX let me play any games?

It might be that you don't have active x enabled on your browser. If this is the problem, try using the Roblox browser. Go to start --> Roblox --> Play Roblox. Then find the game in the Roblox browser and hit play. If this does not work, the problem might have been caused by a Roblox installer problem. Roblox is always working on these problems though so it might work later after Roblox fixes the problem.

Answer 2: Look I think that when you start a game it just stays as a sky and then says " an error has ocourred when starting ROBLOX " and to be honest that happened to me! first of all let me say going to bed and going back on the next day doesn't help! look ROBLOX has probably updated and everyone is having trouble,what I think is just leave it and it will sort itself out.
