I did check this thread before. It might solve the problem with the size limit, but since I am not even able to edit anything now due to the license problem that was presented immediately after the size limit error showed up, I won´t be able to try it. It seems so weird that one day it worked perfectly fine and without doing anything with files it just decided that now I dont have the license.
Sorry about the foto, I am trying to reupload it properly.
As you can see, I cant even add things like "Static Structure" or others in, but I was able to do everything before I tried to get solution of the project I was working on before this problem.
I am also uploading the image of errors that occure after I open the project in read-only mod.
