Ok, it looks like there may be two separate issues here.
For the web version, we've found that the "script error" message is often solved by running the game in a different web browser. The way your error message is being displayed is different than I've seen before, but this is still worth a shot.
For the other versions, some quick research suggests it may be a problem with the renderer. If your computer is currently set up with a very small resolution that may be causing the trouble. I'm not sure if the game is crashing for you on startup, but if not, you can try lowering the game resolution and/or selecting a different renderer as explained here:
