[Evolution] find calendar on new install

["carpetnailz researchintegration org" <carpetnailz researchintegration org>]

I had to reinstall my OS and ended up with Ubuntu 9.04. I copied my
old .evolution folder, replacing the one created when the new Evolution
started up. I can now see my old email and contacts fine, but am
confronted with an empty calendar. 

How can I get Evolution to see the old calendar? It seems to be present
with the others in the .evolution folder but Evolution is not seeing it.

Thanks.
