[Plugin: The Social Links] Does not work

The plug in is broken. The support sites do not help and they do not reply to questions. I would not recommend this to anyone. Here is my original support question:

While using the Social Links plug-in on my website the links connected to the icons are going to the wrong website.
i.e.
If my twitter link is:
twitter.com/myusername
and my website is:
http://www.mywebsite.com

Then when I click on the twitter icon it will create this link which does not work: http://www.mywebsite.com/twitter.com/myusername

How can this be fixed?
