I would like to further confirm the existence of this issue.
I am using the DriverPacks BASE 8.12.5 that is integrated in UBCD4WIN 3.5
When I run the UpdateChecker the LAN DriverPack option stays grayed out.
I did download fresh versions of the LAN DriverPack from the DriverPacks website.
I have tried the two versions of the LAN DriverPack I list below,
both give the error 'Where did you get that?':
Dec 25, 2008 Windows 2000/XP/2003 x86 LAN - 8.12.1
May 30, 2008 Windows 2000/XP/2003 x86 LAN - 8.05.3
Thanks!
