Ok this is how ive got it to work in game for me. do what Blazinfury said and go into the Tycoon-->Tycoon folder. and take the folders Libs, List, Media, Modules and put those into the last Tycoon folder (one right above Tycooncontent). Then take all the files with .lua and .toc and put those in the Tycoon folder (one above Tycooncontent again). Next put the Tycoon folder you put everything into, and put that in your WoW-->Interface-->AddOns folder. Now go to the same folder that has ManaCore, and all the ManaCore_Data_x (x being a letter) and put the .toc file from ManaCore_Data_x and put it into the ManaCore file. Repeat this for every ManaCore_Data_x folder. Now place the ManaCore folder in your WoW-->Interface-->AddOns folder. Then repeat the same steps for LightHeaded, and put that into your AddOns folder as well. Open your WoW and check the addons button at char select and they should all be listed now. Make sure the "Show outdated addons" button is selected just incase you ended up with and old version.
Now to MY problem :) Ive got tycoon in game and everything but even after it does its auto scan, nothing shows up in my tabs on tycoon. Ive done it for 2 days hoping maybe it had to build a database first but still nothing so far, any ideas?
