Help! Yast is F*cked up!

Yast is giving me a crap ton of errors!
yast got signal 11 at ycp file usr share yast2 clients inst_packages.ycp 36
– After starting yast software, it shuts down with that message

Opensuse 11.0 repo is broken I also get.

Help!

you need to reinstall yast. zypper command could do it for you. do a search for zypper as i use it only few times and I found it in some other threads.
