When I load mp3 arrangements the tracks disappear and I can't do a thing unless I close the program and reopen. But then I still can't load mp3. I downloaded mp3 enabler codex and it's the same. I even removed MMMX and reinstalled it!

I used to have Music Maker 12 and I could load anything I wanted including MIDI files!

Even at the bottom where there is the -Soundpool and -Keyboard section, in MM12 there was also an option for seeing my files, but in MMMX there is only the 2 choises I named. HELP!
