So, for everyone who still got this problem.
1. Download the Ultima Installer 2.6. (This can be skipped if you already got the .exe)
2. Execute the .exe and you make the files into a new folder or somewhere else where you want.
3. Download the 2.7 patch (This can be also skipped if you already got the patch)
4. Unzip it.
5. Unzip only the psobb.exe, option.exe and online.exe into the folder. !NOT THE DATA FOLDER, THIS WILL MESS UP EVERYTHING!
6. Start online.exe.
8. Start Game.
9. Have Fun !
*Atleast it worked for me*
There was no 7. !
