Okay, I think I've figured it out by myself... I was tempted to delete this post, since I came up with a solution, but I changed my mind and decided to leave it for a reference point, in case someone else had the same problem in the future. ~)~ I created a new dictionary with the exact same name as the one I was trying to get rid of, then deleted it using the method I described above. Hopefully, it will continue to work...
