Yes from the exact page, and I have an account and registered, the page not
found comes up after I've answered the questions when I click the 30-free
day trial link and then I click next, then it subsequently takes a long
time to load the next page and then it just responds with page is not found.
I'm having a similar problem this morning when trying to download the trial - when I attempt to enter my information and put in the captcha phrase, it tells me the image verification is wrong time after time. I even tried the audio and it still gave me the same error. I emailed Esri support, so we'll see if it gets fixed today.
well I made it through with no problem... I had to answer the questions first and the captcha worked then I was on the download page I am wondering what type of account you have or if there are hidden limitations but the link does work at least for me
