mxdtr.com review: No contact details

I recently found 2 drivers on the website www.mxdtr.com. I didn’t understand why, but the drivers didn’t work properly. And the website didn’t contain any contact information, so I have no idea what measures to take now. I just wanted to ask for help or maybe someone has contacts of admins of this website. I wonder if there are other people, who had the same experience. Can you provide any good piece of advice?
