As a JTag noob, I've been feeling my way round a machine i just bought second hand. It's running Freestyle 2.0 dashboard and I've been using Xexmenu 1.1 to transfer Jtag rips via USB. Everything going smooth until today. Instead of deleting a system update folder from a game I moved it to another location on the HDD in case i needed it. Now my freestyle dash won't boot up at all.

360 comes on as usual but a big grey square appears on top of the 360 logo and i can do nothing from there. Can anybody help with this problem. Thanks.
