Offline Update Instructions:

Download CrushFTP11.zip from our download page. (https://www.crushftp.com/early11/CrushFTP11.zip) Then give it the specific name `CrushFTP11_new.zip` and place this in the CrushFTP main folder. (Same location where you have your prefs.xml file)

Now go back to the admin interface, about tab, and click update now and it will use the offline file to update instead of connecting over the internet.

The files that run CrushFTP are the CrushFTP.jar, plugins folder, and the WebInterface/CrushTunnel.jar file. Those 3 items make up the application. If a file is missing or damaged, CrushFTP won't startup. So you can manually replace those items too to resolve a broken CrushFTP.
