This may be an easy one but I'm pretty new to this:
When I insert a chart - bar graph or line - I can edit it  and change data
points and so forth. Once I come out of edit mode, I can't get back in
again - I get the error message "The server application, source file, or
item can't be found, or returned an unknown error. You may need to reinstall
the server application"
I have done a 'detect and repair' from within PP, and 'repair office' from
the CD. No luck so far. Do I need to uninstall the entire Office suite and
reinstall?

Thanks
Nick
