Go to the link which Pretentious Goblin provided and join the Discord. If I remember correctly (It's been probably around 2 years since I last downloaded a new build), you should be able to find download links to both the old RPGM 2000 version and the new, work-in-progress RPGM MV version on there. You can also ask for help and/or give bug reports there if you have issues with the game, assuming you're playing the MV version.
Alternatively, if you have RPGM MV yourself, you can download the undeployed game files directly off of GitLab (Just go on Google and search "VHMV" - open the top result (should be GitLab - gitgud.io)) under the VHMV folder and set it up through the engine. I'm not sure if there'd be any advantage to that, but if you want to avoid Discord then that's probably your only option.
Lastly, if you're desperate to avoid Discord and are also looking for the original version, you can go to the vh01 translation page (which can also be navigated to from the VHMV page by clicking on "vh_english" near the top of the page and then choosing vh01, or katteban if you're into "that") on GitLab which will provide (at the bottom) links which you can use to find the downloads, as well as instructions on applying the translation from the GitLab. I believe there's pre-translated versions on the wiki linked from that page, but my computer insists that that wiki is a dangerous site and so I cannot verify this claim nor recommend this method. The Discord is by far your best bet.
