PLEASE BACK UP YOUR UI BEFORE INSTALLING THIS ONE.
1 - Back up your Interface and WTF folders.
2 - Extract these two folders in to your main World of Warcraft folder.
3 - Rename the ACCOUNT, SERVER, and CHARACTER to yours. (Doesnt matter who, its just to incorporate profiles for addons)
4 - When logging in do /REFLUX SWITCH GREGS UI. There are several classes I have already setup with ClassTimers and TellMeWhen. They will not load automatically since this UI supports many classes. After the initial Reflux switch you must go in to ClassTimers and TellMeWhen to see if I have one under the profiles. I have Hunter (BM & Survival), (limited Mage, Arcane and Frost), Monk (Brewmaster), and some on DK (Unholy and Frost).
5- SexyMap addon does NOT support a profile system. You must right click the minimap and it will bring up its UI configurations. Click "Use Global Profile" at the bottom and it will set itself.
If you dont like them just disable them to get out of your way. I'd leave ClassTimers up though to track basic things. It works automatically.
Also, the Warlock TellMeWhen setup is from Sparkuggz UI. When I first installed the addon and incorporated his it came with everything I already needed for all three specs - left as is. I have done some work on DK. Hunter BM/Survival and Brewmaster Monk I like quite well how they are now. I have Survival as my primary and BM as my secondary spec. You will have to change those two around if yours are not the same or TMW will NOT show the icons.
