Cube talk 9X not playing videos

Hi All, I am back

I have, succesfully, been using my 9X with Supersports rom for a 1½ years now. But just yesterday I faced situation that no videos are payed anymore. Not from apps, not from web. Not even youtube...
I there some part in system I could update? Or could it be default video player's problem? Didn't find any updates, either, from last few days...
Anyone else with same issue?
