what you could do is take a pic of all the files you have and then paste that in here snipping tool is a great photo capture device and i think wee be able to tell what your missing though any time u replace the file i think itl go to your trash can unless it over rights and rewrite the data and the data code was wrong or the spot you placed the download was wrong also is it possible for you to maybe pm me or post the links you used to download everything so i can give it a shot maybe a download you did was bad id like to help

and a tip for next time always have a back up folder its easy to make copy all the contents of ur fh folder into a new folder on the desktop named something else just in-case your going to do a lot of editing make sure to make a new folder for map backups and your downloads as well

this time if any faults happen you can just copy the contents of the file in ur back up fh and recover ur main fh folder and repair it back to normal
hope to help you out soon
