Hey Chilled!
This could be an issue at Itchs end! If you haven't tried a different web browser, you could try our Patreon download links. (You'll need a Patreon account, but its free to create. The latest free version is 7.15 but 7.16 should be releasing sometime soon).
Also, ensure if you have any anti-virus software to allow the download through or firewall settings. The download can be flagged as a false threat sometimes.
