Yum Source distro Packages Not Working?

[SL6-A1000]

Hey,
My SL6.1 Distribution isn't connecting the the source packages from yum. It says something along the lines of the repo???.xml cannot be found for altrpms & sourceforge packages.

I have already tried using the command:

su yum clean all
su yum update package-list

but that failed to work.

and
su yum makecache

Is there any other way i can try?
Like uninstalling the source from yum then reinstalling it?

Thanks

Could you be more specific with your error messages?
If you could paste the entire errors here in [CODE] tags, perhaps someone could point you ion the right direction.

I fixed the problem, i think it was to do with the trouble i was having with my modem, because i fixed that today & i can now update from yum properly.

Thanks for the help anyway.
