One of our users, Kyle, found a small bug in the files Contact.mde and SalesTrack.mde. The bug has been fixed and the files have been uploaded to this site. Feel free to contact me if you have any questions or issues.
If you have a lot of data in a previous version and need to import the data, you can copy/paste data from one database to another if you have the full version of Access. Again, if you need help just let me know.
