First, you need to realize that unless you had made a backup, you won't be able to retrieve your user database or any print lists that you have compiled. However, you can restore the program and the database to the current versions.

The first step is to re-install First Class from your original CD. (If your computer is running Windows Vista, install using these instructions.) Now open First Class and look under the stamp. If your database date is earlier than January 2005, you will need to go to this page to download and install a patch. If the database is January 2005 or later, proceed to the next step.

The next step is to upgrade your First Class program to the latest version by going to this page and following the instructions. After you have upgraded the program to the latest version, you should update your database.

Click on the Update Database tab. Click the Change... button, enter your current password, and click the OK button. Now click the Check for Updates button to update your database. This process might take some time, depending on how many updates need to be downloaded and the speed of your Internet connection. When it is done, your program and database should be current.

At this time you should probably "repair" the database. It might be OK, but something might have been missed during the update process, so do it to be sure. Click on File > Repair Database.
