Sigma 70-200mm 1:2.8 HSM II AF-problem

Hi,
I had some problems with the autofocus of my Sigma 70-200mm 1:2.8 DG APO Macro HSM II for a while but now it's just brutal. I suddenly stops autofocusing but if you move the focus ring back and forth several times (varies) it have yet come back every time. I can hear a ticking noise when have my ear to the the lens when it doesn't autofocus, it sounds like it's stuck in some way.

Anyone who have encountered this annoying problem? I've sent an email to the service center here in Sweden but I don't think I can afford to get it repaired (no warranty) anytime soon and also I use it for photographing the local hockey team. Bummer...

sigma should have a 3/5 years warranty.
You might be lucky and have it repaired for free.
