The diagnostic Disk or Network Error usually occurs if the user's database is on a server and the PC has lost connectivity to the server.
The solution is to reboot the PC and Compact the database.
Make sure all other users have exited the database.
Click on File, Maintenance, Database, Maintenance.
You may say Yes to do the backup and save it to your backup location.
Once the backup is complete, click Ok.
Once the Database Maintenance Wizard opens, click Next and Next as you will be selecting the default database, as this is the one you are currently in and need to compact.
Tick Compact Database and then Next.
Once the database has finished compacting, select Finish.
Log in to Wage Easy again.
Note: Please contact your IT if the connection with the Network Drive has not restored upon rebooting.
