[SOLVED] No multilib

And I desperately want multilib. I have seen in several places people posting that the have multilib installed. I'm running Slackware 14.2-64 bit
Code:root@caitlyn:~# uname -a

Code: !!! F A T A L !!!
Repository 'multilib' FAILS the CHECKSUMS.md5 signature check
The file may be corrupted or the gpg key may be not valid.
Remember to import keys by launching 'slackpkg update gpg'.And what does this mean?
Code:root@caitlyn:~# slackpkg upgrade multilib

No packages match the pattern for upgrade. Try:

/usr/sbin/slackpkg install|reinstall
