Error message Importing INV File

I am using Money 2005 Samll Business and when I try to import a custom
invoice I receive the following error message.

Money cannot import an INV file that was created before July, 2002. Please
try importing a more recent version of the file.

I just created my file tonight and the properties say it was created
11/19/04 so there should be no problem with the date. I am set up for US
regional settings.

Has anyone ran into this and figured a way around it?

Thanks,
