I'm trying to replace the primary drive in an empeg (just purchased after ~7 years of waiting - yay).

My computers are all linux based. The instructions for applying the disk builder and player software upgrades from a Linux host reference an "upgclient" program, which appears to be part of a tarball called car-empeg-2.0.tgz (or something similar) which used to be on the empeg site. I haven't been able to find either the file or package available for download. Can anyone point me in the right direction?
