ok, I was having the same issue as alot of ppl seem to have. giving me that nomedia thing when I tried this out. heres what I did to work around this issue
First! open up androidthemes on your SD card and make a new file called PulldowndownEditor
second, open up the app Pulldown Editor and hit extract needed files, then type in what you want it to say and hit generate. at this point it will give you another error like cant find file or something. this is ok. now go back in to the file you made in androidthemes called pulldowneditor and you should see a nomedia file and a .thm.
next what you do is this, and this is the key! copy your framework-res to your computer. extract it, delete everything in there but the res file. open up the res file, delete everything in there but the xml file, open that up and delete everything in there but the eri file,. so it should look like this, Framework-res> res>xml>eri. take that framework file and place it in the pulldowneditor file on your SD card in the androidtheme file
next, go BACK in to the app pulldown editor, extract needed files, type in your message and generate. at this point it SHOULD work
go in to MM, hit existing theme, find pulldowneditor, open it up, hit the .thm. then framework and apply. if you do this right, it should work! ya its not as ez as just opening up an app

but it works! and should only take a few mins at best
