Do this...

1. Exit WoW
2. Go to the [ World of Warcraft ] directory and rename [ Interface ] to [ Interface.saved ] and [ WTF ] to [ WTF.saved ]
3. Log in to Wow and click the "AddOns" button at the character selection screen
4. Verify that no addons are listed -- if they are, you're in the wrong [ World of Warcraft ] directory... go back to step 2
5. Close the window and enter the world on any toon
6. Exit WoW again
7. Install nUI 5.06.25 (or nUI+ 5.06.25)
8. Log back into WoW and enter the world... does everything load correctly?

If everything is not loading correctly at that point, post a screen shot. However, I bet everything loads correctly.

Now, exit WoW, install your other addons one addon at a time and log back in after each one to make sure nUI still loads correctly. If it breaks, we'll know which addon broke it.
