XMB not booting

Hi, i hope someone can help please. I wanted to boot the xmb to make sure my install of the latest version works, I've also downloaded the latest firmware from sony's site, but the log keeps hanging and looping on a few lines, leaving me with a black screen. Any help would be greatly appreciated! I've tried uninstalling and reinstalling, running as admin and only emulating pads with mouse/keyboard as I've read this is supported

Thanks so much!
