Have you tried this link:
Trigger Maru Overhauled v2.5
or have you tried another browser? at the top of the download page is this:
If you are experiencing trouble downloading, it could be due to an ad-blocker or extension in your Chrome browser.
Try whitelisting www.subsim.com in your ad-blocker extension, or switching to Microsoft Edge browser or Firefox to complete the download. Thanks.
I did not have an adblocker enabled on my Vivaldi browser, and I still had to whitelist subsim. Edge did not require anything, which makes one wonder...
