The cause of this error is usually related to a rights problem on the server. This could mean that you do not have full access to the server or your computer cannot see the server at this time.
The first thing to check is whether you have access to the network drive. Open My Computer:
- If you see the network drive try to double click on the drive
- If you can open the drive, then try to delete or rename a file in the Abacus directory. A good file to use would be the Law1.cdx
- If you do not see the drive or you get an error message you will need to reconnect the drive or find out why you are having access problems
