It's very strange installing the Bravo Throttle Configurator would cause ALL your extra add-ons to stop working.
If this was FSX ( that's why I asked ), we seen many times some add-on that corrupted the DLL/EXE.XML files, making all the other add-on stop working. However, in P3D4, this is very uncommon, since each add-on has its own separate add-on.xml file that others are not supposed to touch.
Does the Bravo throttle installer use the add-on.xml method ? Have you tried starting the SODE Platform Manager, it might tell you something about issues with the files.
