Premium Trial issue

I keep trying to initiate a free trial for premium anchor design but it leads me in circles and so I am not wanting to buy a month subscription because every time I try to get the trial it brings me to hilti profis without actually upgrading me. So I am wondering how to fix this and why it is happening before I am willing to pay money for the premium. It basically creates a loop. Where I go back to hilti profis and then it says to upgrade to premium and the process starts all over.
