Just because an addon is "out of date" doesn't mean it doesn't work. Thankfully. It may use API that's never been changed, so an update wasn't ever necessary.
As much as that bugs my OCD, it's the truth. It also sucks to use an outdated addon and learn to love it... and then it eventually breaks because the API changes and the addon author has abandoned their addon....
BUUUUUUT... if you actually try the "out of date" addon, it has bugs right away, and you comment on the addon's page... and then give someone a decent amount of time to respond... but no one does... you can go to the addon help/support forum, be very specific with whatever issue you're having, and ask for assistance. There's a few authors that are nice enough to maybe actually help.
But... be sure to try the addon yourself before saying it isn't working.
Good luck!
