HELP!! Handcent SMS

[forever.hk]

i downloaded the handcent sms app from the market as well as the tone picker so i could customize my ringtones per contact. when i open tone picker in my contacts or handcents sms when i hit select ringtone it use to give me two options 1-android system (the stock ringtones) 2-tone picker (my music and ringtones on my sd card). there was a little checkbox on the bottom of it that said "check to use as default". I accidently checked it when i was adding a custome ringtone to one of my contacts, and hit android system and i don't know how to get back my tone picker onto it, like how it was before. does anyone know how to change it back?
