Recored for 22 minutes, but only plays back the first few minutes

[aquavalver]

Can anyone help? I downloaded the free version and recorded 22 minutes of chat with a friend. When I played it back it played for the first few minutes fine, then the screen went white, then a few seconds later, it played the first few minutes again and then the same again! Anyone know why?

 

If it's because the free version only records the first few minutes, it should have mentioned that, so then I would have either bought the full version or never used it in the first place.

 

I hope that someone can help please? Thanks!
