Lite-on sohw-1633s firmware update issues

this seems to be a hugely common problem with these drives…i got the emachines computer from best buy that came with the sohw-1633s bgs4 burner. i’ve looked at all kinds of threads on many different forums to help me figure this out, and every one of them points to codeguys.rpc1.org, which seems to help everyone. however, the site seems to be down.

can anyone offer any help?
