Ok, so what i am going to say is maybe going to surprise you, or maybe not?
Anyway, got it fixed, but i don't like the solution. What i basicly had to do, is switch the language from slovenian, which is my primary language, to english, and the second i did that it was able to update, isn't that a bit strange. I assume something is wrong with the translation or it's just a bbug, but it has to be checked. Didn't have to reinstall though.
