Unable To Play Video. MP4

[Gosx10i]

As the titlke says.

I was able to play these clips on my phone yesterday, last week, but as of today, all it is saying is unable to play?

Any idea guys?

Also, is there a file association reset somewhere on the handset, setting, as so to try and get the thing playing MP4, Mpeg4 again?

Sorted and playing them again.

I knew the answer, i was jusy hoping someone knew how to re set the file association parameters.

Full wipe, re set which is a pain in the rear & hours of re installing!
