Something similar has just happened to me. Promoted to League Two and in the new season I've not had any fixtures scheduled and by the looks of it, I'm still registered in the Vanarama National (Entered into FA Cup 4th Qual rd and FA Trophy). I'm currently attempting to holiday forward to the end of the season to see if this will refresh. I'm hoping this isn't 100 hours down the drain
EDIT - As I am holidaying forward I'm noticing the European leagues have moved forward as suspected but even the premier league has not rolled over. It seems the entire English pyramid has gotten stuck in the previous season
