Actually, I've got it working again. Here's the thread where the solution was solved:

It had to do with ghost windows and double renaming.

Here's the two rename functions that got me working again. Call the "alt" one first, then the regular one.

// Command version of the same function to rename all of the World of Warcraft Windows
<Command RenameAllWindows>
<SendPC local>
<RenameWin "World of Warcraft" WoW1>
<RenameWin "World of Warcraft" WoW2>
<RenameWin "World of Warcraft" WoW3>
<RenameWin "World of Warcraft" WoW4>
<RenameWin "World of Warcraft" WoW5>


// Command version of the same function to rename all of the World of Warcraft Windows
