I'm kinda stuck so I would really like help. Thanks

You can also point your update site to:

http://beust.com/eclipse-5.11.0.28

If you take a look at the mentioned location in your browser, you'll see that the old jar you're requesting isn't there anymore. Luckily, you can still download the old version from the TestNG website and install it yourself.

It's because version 5.11.0.28 is not on that server anymore.

try org.testng.eclipse_5.12.0.6.jar

(sorry, part of the question was in the headline, you asked for an older version...)
