DS 6.9 SP2 "Have Disk" still does not work

I downloaded and installed DS 6.9 SP2 on a new server. There is still a problem adding drivers to the boot image. I need to add WinPE NIC Drivers for an HP Mini 2140. I clicked Have Disk and pointed to my driver and nothing works.

With DS 6.9 SP1, I had to install Maintenance Pack 1 (MP1) in order to get this to work.

I can see my driver files in \\dsservername\eXpress\Bootwiz\platforms\Winpe2\x86\Drivers\CUSTOM\Drivers\yk51x86 but when I compile nothing works and my driver still does not get in. I reboot, restart services, etc, etc and nothing.

Wasn't SP2 suppose to resolve this issue.

Is anyone else out there experiencing this issue with SP2. Thanks.
