Ok, so I added myself rights for a new folder!
And from there, I could delete the file I tried to delete.. but the problem is, now I cant use loadlines from the documents there since the folder isnt listed in server options.. and as far as I know, you can only add subfolders to leves/ in the folder options.
So if im wrong, and you can add other folders there, please tell me how to do.. if not, am I screwed when it comes to deleting a file?
