Errors with the [p] key in game engines

im doing this tutorial:

It says press [p] to run the real time simulation. i pressed it, and shortly after, it said blender wasn’t responding and i had to “end now”.

how can i press [p] without it screwing up the program?

Quite old tutorial
What version of blender are you using?
Anyway, open Blender with the standard scene ( cube) and just press P key
Still those messages? If not, the game engine it’s probably fine.

im using 2.37a.

tests soemthing before returning to browser

oh wait.
i think the problem is that im running the blender thing from my usb. cos when i run it from my computer c:/, it works completely fine…

ill post some updates if i still have errors
