I get the same error on that one too. Seems something has changed again with ciphers. I tried a number of music downloads just now and couldnt get them to work either. I was able to get some video downloads to work to verify it wasnt just broken.

Solved

SignatureDecipher.php, line: 183

if($deciphers && count($deciphers[0]) > 2){

changed to

if($deciphers && count($deciphers[0]) >= 2){

because for some reason $deciphers[0] contained 2 elements only.

I didn't fully inspect the source code for this project and I don't know if that will negatively affect something else, but it seems to be working great for me.

Someone with more knowledge should do a PR.
