Okay. Well, I've tried everything. I renamed the folder as anyname_theme.lwtp (anyname was just for testing) and it stays as a folder, it doesn't change at all except for its name. I cut and paste it anyway. I paste it into the themes folder, and it's still a folder file, I go on Limewire and click on my theme, it's in the list, but when I click on it it says it doesn't exist (I'm sure there was a picture of that error earlier in the thread).

Why won't it change to a .lwtp file?!
