Timeslips can usually fix this error automatically, however a reboot can also correct this error. However if you’re working with an older version and it persists, do the following:
- open the BDE Administrator in the Control Panel
- click on the Configuration tab in the left panel
- expand System and click on INIT
- look for MAXFILEHANDLES and MEMSIZE. Each should be at least 200.
- restart Timeslips
