all good now.. although not sure what did it.. I re installed os3.9 , install bong bag 1 and 2 only, and i did not install rom update on 2nd bong bag and I and just replaced the rapid road usbhardware drivers.. I and thinking my self it was probably the the usb 1.7 drivers that did it, Yesterday i did install them but also installed thors mmu.library too which destroyed the system when rebooted.. so now my question is should i install that bong bag 3 and 4 combo update?
