Photoshop :: Error Trying To Use Warped Text Because Type Uses Faux Bold Style

I'm using PS6. Trying to use the warped text function, and I just get the error message "Could not complete your request because the type layer uses a faux bold style". Well, normally the answer is to just turn off the faux bold style with the flyout menu on the character window or on the top of the screen. But the problem is that it's already off. I've tried resetting all my tools back to the default settings. I've tried using different fonts. (currently using arial). Nothing seems to work. No matter what I try, it just continues to throw the same error each time.
