The all.ini file should have the load.ini for each new map listed- if you used a self installer such as the slot map uses, your all.ini should be alright.
The list I showed is only for the config.ini.
It's important that the name that appears in the FMB list be the same as the one in the config.ini and in the mission file.
If you do a search here under "QMB+" you should be able to find more detailed instructions.
In short, three things have to jibe, once the map is installed;
The map name in the config.ini list
The map name in the mission file
The map name in the all.ini
