Thats because ACRE is too old and was never updated to the latest API of teamspeak!
But even though you are probably dead in a ditch somewhere....
This is an unofficial edit by myself. It uses the new api 20 of teamspeak. It is unsigned, but who signs anything anyways haha.
All work on ACRE has been the respective authors NouberNou and Kju and I take no credit. I simply hex'd the dlls and edited the addon to accept the new api, something they would have done much quicker and better than me!
