Business Contact Manager for Outlook (2007) is refusing to open contacts. This problem appeared this morning on every machine (Windows XP SP3) on our network.

The contact list does populate as normal, and contacts can be printed from the context menu, but the form that displays the contact information does not display, and no error message is thrown. I have turned on logging for BCM in the help menu, but nothing is being generated (or, leastways, I cannot find it anywhere).

The SQL services appear to have started as normal.

Anyone come across this before I take a deep breath and go with my boss' suggestion of "just reboot the server"?

Any other information you need?

Thanks.
