[xwiki-users] Very basic help needed, please!

Greetings All, I recently downloaded the XWiki enterprise package that was as fool proof as they came. I read through all the instructions then carefully (or so I thought) installed it. I went to go Open "start wiki" and a black box appeared, immediately the box closed, I tried again a few Times but the same thing continued to happen. I tried to go to "my wiki" in IE and it wouldn't Load. I have no idea where I went wrong. I tried to uninstall so that I could reinstall it and try Again, the "uninstall" option from my start menu (I'm using windows 7) wouldn't work. Any Help or insight would be greatly appreciated. Thanks for taking the time to read this, Alex.
