Library Catalogue Still Down

Yes, we still don't have the library catalogue working. To give some background: the initial error that deactivated the catalogue has only ever been seen once before by our vendor technical support team and related to how catalogue information was copied onto the web. To solve (hah!) this, they came up with a piece of software whose only function was to copy data. Before it was run, vendor technical support deleted all catalogue data. However when we run the sofware, we get an error message saying that we don't have permission to access the directories where catalogue data is stored. But we do (how else could we delete the data in the first instance?). Unfortunately the problem can't be solved by retrieving catalogue data from the recycle bin, so vendor techical support are currently scratching their heads. Stay tuned.
