Yum Error and RHN Problem

[Scott]

I recently updated to FC2 Test2 and then I immediately updated the 249 
out of date applications.  After updating I rebooted the computer and I 
have encountered 2 problems:

RHN:
I do not have the RHN icon on the panel.  When I try to run the RHN 
configuration under System Settings nothing happens.  When I run RHN and 
RHN Alert Icon under System Tools, nothing happens

Yum:
When I try to run Yum I get the following error:
Traceback (most recent call last):
 File "/usr/bin/yum", line 22, in ?
   import yummain
 File "/usr/share/yum/yummain.py", line 22, in ?
   import clientStuff
 File "/usr/share/yum/clientStuff.py", line 18, in ?
   import rpm
ImportError: /usr/lib/python2.3/site-packages/rpmmodule.so: undefined 
symbol: rpmdsBT

Any help would be appreciated.
