Alright,
Did as you said >
Runned the game as admin,
allowed all permissions,
deleted version.txt again and runned the updater once more,
The updater said, that it can't find LastMoon.exe file, which was weird since both of them are in same folder,
Version.txt file was empty, nothing is written in it.
-----------
For a second I thought,
if it is 'updating', then I am missing some files.
If that's true, then I need updated LM folder, right?
Can any of you send it to me?
