Sorry if it's been answered in posts but I couldn't find it.

I went to play after not playing for about a month on PS3 and it's saying
"Cannot Launch FFXIV please register the promo code that came with your package"
When I go to enter the registration code (I have the physical copy) it says that its expired? It's the only code I have and I've been paying for it for months so its not like I didn't pay for a month or anything. Any one have a fix for this or is it a contact SE thing? Thanks
