If you are experiencing problems with the download being corrupted please try using 7zip to unzip the file. 7-zip.org
Make sure your downloading the files from here on the modb.com and not the totalwarcentre link as they don't work.
Also if your browser isn't downloading them, try Internet Explorer 11 IE11 works fine for me.
If there is still an issue please message me or comment, although I am very slow at responding at this time.
