Only two problems so far, not too bad considering my usual shoddy work
Looks like you are trying to open it directly from the website and not saving directly to your machine. You should right click on the link in this thread and select "Save As...".
Once it's on your machine (anywhere will do) it should open ok.
The other problem some people have had is a security one, you'll maybe need to check that the file isn't read only under the file properties.
As a side note, you'll need to enable macros for this .mdb file for it to work.
I hope this is relevant to the problems you have.
Cheers
Joe
