So i've downloaded this app and purchased the full version. I managed to added my own videos and see them through mivtones. My problem is, i can't set a video to anything, not even the default. I picked a default video and any calls i get, its just my regular ringtones. I'm guessing that some ringtones that i've downloaded through cydia may cause a conflict with this...but i'm really not sure. Anyone had the same problem with this?
