UR won't link items!

[dasymington]

When I try to link items using Alt-drag, copy and paste or the Link/Move context menu item, I get:

Error linking item(s): near "SELECT": syntax error

This is happening today after upgrading to version 2.0e yesterday. I've reverted to 2.0d, but the same thing is happening. I've rebooted and it still happens. It's also happening with a small test database, so it seem to be something to do with the UR installation rather than a database.

How can I fix this?
