Open the debug log by pressing Windows-R and in the Run dialog type:
Code:
"%appdata%\xbmc\xbmc.log"
(including the quotes). Click OK and the log should open in Notepad. Copy and paste the log into http://pastebin.com/ and post the link it gives you here.
if you have a bluray/dvd in the drive remove it and try again.
