Buy button website not working for me

[Beefest]

Hi, I can't buy SaT because the 'Buy Now' button on the website is somehow not working for me (both Full Version and Small Stakes). I tried in Chrome and in Firefox. I'm pretty sure I bought it last year for a few months without problems. 

Any idea what might be going on? Did you hear this from other people? Not sure if it's the website or my pc but I don't seem to have issues with any other buttons on your website or other websites.
