[Fedora-Bangladesh] Problem installing or updating softwares in Fedora 13 beta

I'm facing this problem when I'm trying to install or update anything:

[nirjhor at localhost ~]$ su
Password:
[root at localhost nirjhor]# yum install kate
Loaded plugins: presto, refresh-packagekit

Trying other mirror.

It keeps trying different mirrors. How to solve this problem?
