Notice:
This Magento extension is discontinued starting May 1st 2014.
There will be no support and no updates, I will just leave it here for posterity.
You can use instead the new version: <a href="https://github.com/tzyganu/UMC1.9">UMC1.9</a>
It is not backwards compatible, so I recommend unsintalling this extension and installing the new version.
All open issues from this extension were moved (if not fixed) in the new version.
