It seems that you're using an outdated browser. Some things may not work as they should (or don't work at all).
We suggest you upgrade newer and better browser like: Chrome, Firefox, Internet Explorer or Opera

Every time I go to update, I need a new downloader or something, let me update ffs.
Are you trying to update from 1.4 to 3.0.2? I tried Verify/Repair and that didn't work for me either. I had to uninstall and reinstall for the Anniversary Edition/3.0.2 update to take. A pain I know, but I didn't have to download anything else. I hope this helps.
