Here is what I get when I run up2date:
[root@msd deiss]# up2date -r -l
Successfully completed anonymous registration. You do not need to use this

There was a fatal RPM error. The message was:
error reading from database
I don't know how to fix this.....I don't know what caused this.....
Just for fun, I tried the Windows solution to this type of problem: de-install
up2date, re-install. Voila. It's working for me again.
