Hi, I've got some problems while booting BT5, I'm trying to run the live DVD environment but can't get it to work.

I boot from the DVD, chooses "default boot text mode", then some text passes by and after a few minutes I'm asked to write "startx" to launch the graphical interface. After writing "startx" the screen gets black but after a few minutes the BT background shows and the mouse cursor. But nothing but the background shows, no menus or anything else and the mouse cursor starts to flip between a clock and the regular arrow. After this nothing else happens, the mouse cursor keeps flip for hours. So, I'm stuck here and don't know what to do.

I added a image to show where the screen seems to get stuck.

Anyone who has any suggestion what to do?
