I have an error when i start the game (the file fsgame.ltx is corrupted (it contains duplicated lines) please reinstall the game or fix the problem manually.). I installed the complete 2009 modpack then uninstalled it and then tried to play regular, couldn't save it, tried to fix it, messed up cant start the game now. I have already uninstalled and reinstalled multiple times.

That is my folder as seen in notepad

Try overwriting what you have with mine: If that doesn't work, try replacing "C:\|Users\Public\Documents\STALKER-SHOC\ " with "C:\|ProgramData\Documents\STALKER-SHOC\ " in the above.
