Some people have had problems using the new version in an old save. The 'fix' has been to uninstall the mod, launch the game and open a save. Then make a new save and exit the game. Re-install the mod and open the new save. Depending on your level, Brisa may come to you after awhile or be at the sniper shack.
As a side note, if you are using COCO - that will break the mod, so I would suggest JIP Companions Command and Control if you want that kind of interface for Brisa - but then I would say that cleaning an old save of the Brisa mod, like I described above, would also be advisable because JIP is based on the new version.
