I'm sorry for the mistake with the link. When the plugin was in it's early stage and I was a complete beginner(that's my first and only plugin) it was containing a footer link and a non-GPL compatible license. That was present until version 2.0 when the plugin got suspended. Later i only made version 2.1 just to remove that old link and put GPL license inside. Then the plugin was unsuspended and everything was ok for a long time later on.
As I was doing recently some upgrades(now plugin lets you change size and colors, also improves compatibility) I accidently used old files as a base (my local copy was 2.0 instead of 2.1) and releasing version 3.0 has reverted that link and license fix.
Another problem recently was my hosting account being suspended due to very high cpu load(suspended on hostmonster, hostgator and inmotionhosting). Now the problem is fixed and the website is hosted as a vps in inmotionhosting.
I've already commited version 3.2 in svn which is removing a link from the footer and contains GPL license. Now I'm already writing with email@example.com to get my code reviewed and plugin unsuspended.
I hope you're enjoying my plugin and soon lots of new improvements are going to be done!
