Discjuggler = max speed 4X

[Snowcrash]

I have a new LG 24/10/40 burner (model GCE 8240B).
It was working with no problems before I installed Discjuggler 3.50.818.
Now the max speed in all burning programs I have is 4X. I cannot select a higher burning speed in any of them - Nero, Adapted Easy CD 5.1. Both of those programs report the max record speed as 4X now in the Drive properties tools. I've tried uninstalling the burner in Device Manager and reinstalling it, uninstalling and restarting the computer, I've uninstalled Disc Juggler, I've reinstalled the ASPI drivers - nothing helps.
