Zachary:

    I can only give you some good pointers in troubleshooting, that 
should let you clear this up.  But first, a couple of pointers: It is a 
good idea to give some more information about errors.  In your case, the 
version of yum you are using (in a terminal enter rpm -q yum which will 
give you the complete package name.  Also what can be critical just 
after installing a new version is whether you did a clean install (i.e. 
deleting old files, except for home directory) or update.  I assume you 
did the latter.  On to the fun!:

Let me introduce to you the strace command
from the terminal enter :

strace yum update

will provide a step-by step of processes while yum is executing.  When 
the program stops look for  lines that give an error (often 
enoent:missing file xxx.xxx..xxx) This will usually point you to the 
problem, though you may need to figure out what package will provide the 
missing file.

Just out of curiosity, you didn't install the brand-new FC4 test 1 did 
you?  Anyway, you should check to see if up2date can be used instead of 
yum, at least until you get yum fixed up.

Good luck!
