Add a little more details to your post william, it will help out greatly, basically more then 1 sentence LOL. But make sure of this at the least, that the MBII folder is in the GameData folder (the folder that contains the jamp.exe). It does NOT go into your base folder or mme folder. You may also need to set permissions for jamp if it is not finding the executable, todo this, right click on jamp.exe Properties->Compatibility and check the "Run this program as administrator" box. Whatever OS you are running, it should be able to "find" jamp now.
