Why is my merchant outbox telling me to create a store when I already have one?

[TishaRogue]

I will start with saying this particular problem has never happend to me before and I have always used the 3rd party viewers to send my products to MP. 

When I open my merchant outbox I am getting a messege saying that anyone can sell on MP and to create a merchant store. I cannont send my items to my already existing store. I have checked the MP store by logging into it and making sure there are no red flags put on by the labs and to make sure the page still opens. The store is still there on MP but when i try and load the outbox it doesn't seem to be finding it. 

Please help as any new items cant be listed until this is resolved.
