game won't work on my desktop!

[Annamaria]

A whole new thread i know, im sorry!
But really, I can't get Pirates to load on my new desktop.
I can get it on my laptop, but i used to have toontown on that so im guessing im missing something on my bigger comp.
When i first tried to download it, it wouldnt run and said i needed to install some java thing. (my dad "Oh no you dont need that!") So i clicked off and after the second or third time it never popped up again.
pretty sure this is what im looking for but if anyone has any other suggestions or a link to this java thing id really appreciate it.
Its an xpc.. i dont know what that means but the pc is ver-ry tiny. Also it has Windows Vista.
please and thank you very much lauren
