You can create an account for yourself by logging into your database using for example Navicat and then go into the accounts table in your logon database and make your account.

Also if you are going to host a public server using a repack, don't bother running a server at all. Running a server without the knowledge on how to run it is a bad idea. You need to know how to compile your own server, how to maintain it and etc. before starting your own server.
