G'Day Joe,
South Sudan is relatively new.
If is not in the Prefix table for older copies of Logic9.
Update to the
latest version of Logic9 and you should be OK. The South Sudan updates are in in the Prefix Table.

PS: It is very helpful if you include the version of Logic you are using in your post. Use Help, About to see your version of Logic. The latest version is 9.0.60. It is also good practice, that once up to date, you apply all the updates and keep up to date.

You can help by posting images of
any errors and including your
Logic version.
