Help Does anybody have this sudden problem with BBC Iplayer?

[Lefthand]

All of a sudden when I try to access a downloaded programme on Iplayer it crashes. At first all the downoladed programmes disappeared from the list and I just thought they all expired. I've re-downloaded some programmes, but every time I tap the "downloaded" button I get the "Unfortunately BBC Iplayer has stopped working" message. Has anybody been experiencing the same problem? Any solutions?
