I started the launcher and it tells me i don't own the game but I do

The way to fix this with the most success is to:

* Uninstall live EFT and the BSG launcher

* Install the BSG launcher and game again

* Start live and reach the menu, exit game

* Start SPT

After performing the above don’t move the live EFT folder anywhere. If it takes up too much space (and you don’t intend to play live), you can delete the `EscapeFromTarkov_Data` folder to save 30gb+ of space.
