Can't buy Modality Pro

Hello everyone ??

Since yesterday, I try to buy the Theme Modality Pro for USD 50.
But it doesn’t work at all! As soon as I fill in the form with, the Buttom on the bottom starts to be inactivated and a wheel is spinning nonstop. Regardless, which Browser (IE, Firefox, Chrom) or PC (Mac and PC) I use, the problem still exist.

I tried also to fill out the Support Form on the Website, but here the same problem. So, what can I do?? Does anyone have an e-mail adress of that company so I can write them? ??

Thank you very much and kind regards
