help with MMM-GoogleBirthdayProvider

[ilikestuff]

When I add the module to my config, the mm goes black, not the usual ‘create config’ error, just a black screen that I can’t exit. I have to edit the config, and restart mm.
Adding the calendar url is ok, only adding the module causes error. There were no errors during the install, including generate token

 {
 					  url: 'http://localhost:8080/mmm-googlebirthdaysprovider',
 					  symbol: 'birthday-cake',
 					  color: '#f00'
            				},

{
                   module: "MMM-GoogleBirthdaysProvider",
                   config: {}
                },
