Bought a new SD card and now it works pefectly, thanks guys for the help

That's not done anything :/ I think I may have the wrong SD card! Thanks though.

So I'm a complete noob when it comes to this stuff but I decided I wanted to learn so I bought a raspberry pi. I set it up just like it says to however it seems to skip the boot up sequence where you enter the username and password and instead goes straight to some weird desktop, it has the xbmc log...
