The item store is down due to new regulations in europe called VATMOSS.
This new law states that we have to charge VAT for every sale via a rate of the location of the customer.
Because I don't know where a player is from and I don't want to store such information in our database we took down the store for the moment. I am working on a solution but since I am very busy with BouncerVR also I can't give you an ETA.
