Was looking into that too.
It looks like v1 is not working anymore:
$ curl -H 'X-Auth-Token:(apikey)' 'http://api.football-data.org/v1/competitions/'

<head><title>504 Gateway Time-out</title></head>
<body bgcolor="white">

</html>
Api v2 does work:

But unfortunately the v2 commands have a new syntax and probably different output, so the code would need a change.
The changes are probably for the better:

but until someone spends some spare-time, we will have to do without it.
Yes that explains a lot. Now i understand that its not working. would be nice if the author would update it.
