If you like us use mumble and found that today it has stopped working don't fear i have found a fix!
It's to do with the certificates being out of date, whats more annoying is that the help section on mumble is wrong. Heres what you do to fix it: On this thread will be a file >DOWNLOAD. Now open your mumble folder (To find your mumble folder, right click on the mumble shorcut >properties>open file location)
Then you want to rename the mumble.exe to mumble_OLD.exe (to do that right click and RENAME)
Then drag the new mumble.exe that you just downloaded in to the mumble folder.
It should then work for you :)
