solidworks 2018/19 "Download problem" error message

I have been given a license key for solidworks 2018/19 by my university but when I try to download it I get the same error message each time. Within a few seconds of clicking download I get the message "Download problem" and this gives me the option to download the files manually, however manual download links give me a further error message saying "The website declined to show this webpage". I have attached screenshots of these two error messages.  I have also tried turning off all my anti-virus/firewall/popup blockers etc but that seems to make no difference.

Any help in resolving this problem would be greatly appreciated.

Thanks!
