From your Jewel Home Screen, go to Maintenance / Properties / General tab. After inserting your USB drive (also called a memory stick, thumb drive, removable storage media, etc), click Browse, and in the window that pops up, select your USB drive. Click OK twice to return to the Home Screen, and try backing up again.
Go to Maintenance / Properties / General tab. With the USB drive inserted, click Browse, and select your USB drive in the window that pops up. Then click Make New Folder, and type a name such as "Jewel Backups". Click OK twice to return to the Home Screen. All issues should now be resolved.
Go to File / Utilities / Restore Full Backup. Find the location where the backup is stored and select the backup (.jlb) file, then click open.
First, go to File / Open Database, and look in the Documents\Jewel folder for a file named "Your Church Name.mdb". Select and open that file. Look at the dates of last offering and last check in the lower right-hand corner, and the current month in the lower left-hand corner to verify whether this is the correct database. If it isn't, search your computer for other files with a similar name and check them. If you still can't find your database, you can restore your most recent backup, if that's more recent than the database(s) you've found.
You are probably trying to open the database with something other than Jewel. Remember: Your database can ONLY be opened IN JEWEL!! You will get error messages when trying to open it any other way.
From Jewel's Menu Bar, go to File/ Create Backup Copy. This will back up your database to the drive specified under Maintenance / Properties / "Create Backup Copy" Destination, the same location you back up to at month end.
Jewel databases are generally kept in the Documents\Jewel folder. So in Jewel, go to File / Open Database, navigate to Documents\Jewel, and look for a file with your church's name. If you see it, open it.
If you don't see the file there, try searching your hard drive or your OneDrive for your church name, to see if you can find a database (.mdb file).
Sometimes when Jewel or the computer shuts down unexpectedly, OneDrive makes a backup of the database with a new name. Then when Jewel opens the database with the old name, data is "lost". Go to your Documents\Jewel folder, and look for .mdb files starting with your church name. Open each one to see which has the most recent data, and use that one going forward.
