Hello @Owendavidrhys1985 I’ve checked in our system and I could see that you have an active Premium subscription already (and the payment was authorised on the 4th May).
Do you have access to that account? 
Thanks

Yes I do but it won't let me activate my automatic renewal for some reason 

Yes, I can see that the renewal was aborted. You’ll need to wait until the current billing cycle ends and once it turns to Free again resubscribe.
Apologies for the inconvenience.

That means I'll have to download all my 300 odd tracks again from my favourite music though doesn't it,? Or is there a way around this? 

Downloads will remain.
However, I recommend to contact our Deezer Support Team and ask one of our agents if there is any way to resubscribe before the period ends..
Thanks
