Normally you would need to download Microsoft SQL Server Management Studio to do it but I attached a small script below that will restore the 7777 and 9999 users.
Just download and extract the zip file. Then run the Restore777.exe file inside. After it runs try to log into the software again with the 7777 password.
Its usually a good idea to leave those users in the system until you get further along in the setup. With adding Managers etc…..
Hope that helps
