We got a SLED 10 Desktop and Server edition cd from a technology conference a few weeks ago and now when I try to install it, it errors. The error says....

"Package was not found on the medium Err:Package SuSE Firewall2-3.4_SVNr 142-7.6 fails integrity check. Do you want to retry downloading it, or abort installation?"

Does this mean that the installation disk is junk or is there some way to work around this?
