Package Manager and Yum Don't Work

[Jesse Petre]

Hello,
I just installed Fedora, and I'm having a few issues...hopefully someone can
help.  When I go to Add/Remove Programs (package manager) it says that:
"Another application is running which is accessing software information" and
then closes.  Also, when I try to install something in Yum, it returns:
Loading "installonlyn" plugin
Existing lock /var/run/yum.pid: another copy is running. Aborting.
Everything is sitting idle, and I'm not running any programs.  What's going
on?  This is a fresh install...

Thanks,

Jesse
