Cannot register on website

Hello Webmasters,

I would like to report a 'bug' with website's registration process.
I've sent you an e-mail but I guess you haven't recieved it yet.Anyways I will write here what I wrote in that e-mail:

Good evening,

Friend of mine asked me for help when he tried to register on sasclan.org website. At some point of the registration process he came across Security code which he had to re-write from the given picture in to the empty box below. The security code picture looked like this: http://www.webpagescreenshot.info/img/435968-823201224409AM
He tried to register using chrome and firefox but with no luck. I myself tried to register with same browsers and got same 'broken' picture.
If you would be kind and take a look at it, it would be appreciated a lot.

Friends xfire username (in case you need to contact him): kazik90215

Thanks in advance.
