I wrote this add-on for the site that I help run, and released it on here for free so everyone could benefit from them. Everyone that has had a problem with it has gotten an answer, and I haven't gotten a dime for the countless hours I've put into writing and supporting my two add-ons. You can buy an add-on that does a little more and has support from the developer for $40 USD:
http://xenforo.com/community/resources/1652/. I think we've got a really great community here and I really enjoy writing add-ons, but I simply don't have the time to do so as often as I used to. I'll do my best, but please don't complain about a free service.

As for your problem with 1.5, I'm not sure why it wouldn't work (we have a 1.5 board running and it works fine). Can you give me any specific error messages that show up?
