Ok, this is probably a simple problem and I'm just over looking something; while recording a new track I ran out of space on my card, so I went back to erase a track I didnt need anymore to make room, and it said that it erased the track, yet it still says that there's 0:00 time remaining on my card. The track is gone as far as I know, it is not audible, but it didn't release any time back to my card, whats going on here?
