Document Not Saved

[HMH]

An excel document, coupled with a VB addin, is giving me this error message
when I try to save it using CTRL+S. Any ideas what may be causing this would
be great.

P.S. this happens even when I try to save locally, so it is not a network
problem.

Well I figured it. For any other users who experience this problem, check
your add-in. It may need to be "re-loaded".
