Fsbuild-2 Flight Planner

I recently tried to update the FSB navdata with the 1308 info from navigraph. I ran the installer and pointed everything to my main FSB folder. I look inside the FSB folder and all the new files are there, HOWEVER, there are also files that are designated fsb_nav, fsb_stars... and so on. I found that after updating the database in FSB that I still did not have any of the new nav data in FSB. As an experiment I tried changing the Navigraph file STARS to FSB_Stars and removing the original FSB_STARS file(note that all the original files have a lock symbol over them, I do not know why).
After this, viola, I now have the new STARS in FSB. So, my question. Do I need to rename all of the Navigraph files and remove all the FSB default files to update the database? There is nothing that I could find to explain this process so some clarification would be much appreciated. What files do I need to rename or replace exactly, some of them are named differently than their FSB counter part and aside from the SIDS and STARS files I am really unsure what to rename and replace. Absolutely need some clarification here.

Also please note that your description in the FAQ regarding updating the navdata is now completely wrong. FSB doesnt host anything anymore.

If you want to update the AIRAC you must have the 2.4.x version of FSB...
