I can install rpms easily through up2date - I just can't install packages I downloaded myself (i.e.  ati driver, thunderbird) Any one know a solution?

I had the same problem with FC2, and I had to reinstall it.  I removed a 
package that system-package relied on.  It may be possible to get the 
program to run without a full reinstallation, but I decided since the 
system was just installed it was easier for me to reinstall FC2.
