Group buttons

[sivy]

Need some help getting group buttons to work.....This is what I have done

1 I have downloaded the latest version
2 I unziped the file cut and pasted it to its own folder within the addons folder
3 I loaded the game and it does not load, I dont get an addon button in the lower left hand corner.....I have loaded others this way and it worked......I recently loaded ace, aceheal, ace gui, decursive, timex, outcast, ct mod, duf, dab and group buttons.....then all of these were in the addons folder only the ace, aceheal, ace gui, timex and decursive were in the addons portion of the character selection screen.


questions

do you see something that I'm doing wrong
do I have to take the blizz files out of the addon folder?

thanks
