Minecraft Version: 1.5.1

ComputerCraft 1.51 is does not mean it is for Minecraft 1.5.1, it is just a happy coincidence that the CC version currently matches up with Minecraft's version. ComputerCraft is not yet for Minecraft 1.5.1 only 1.5…

ComputerCraft 1.51 is for Minecraft 1.5, not 1.5.1.

Didn't know…thanks mate. :/

This is why Mod.acceptedMinecraftVersions exists, Cloudy.

It's gonna crash either way. If people lack the reading comprehension to check what version a mod is for, this won't help.

That way is supposed to display a more readable error message.
