Thank you! I dont know which one but i will definitely try something else. This is unbelievable, i keep trying to realize what happened.
I cannot even fix anything because i changed my computer with an imac and as everybody knows Paint.net dsnt work on mac (which is so hurting because im in love with Paint). But because im in no mood whatsoever to try anything else i think ill install windows too on this mac so ill be able to use it again, i so miss it.
