Can you send a screenshot? Try updating Tampermonkey to the latest version. If that doesn't fix it, update Chrome to the latest version. If you still can't download it, try uninstalling Tampermokey then reinstalling it. If that doesn't work, uninstall then reinstall Chrome and install Tampermokey. If none of the above work, you might have an extension that prevents extensions from installing userscripts from being installed. If you can't access greasyfork.com, then you have either a firewall or proxy that blocks access to that site.
