I'm a premium member, and I currently have a linden home. I'm trying to bid on a larger mainland parcel in an auction and it is telling me I should update my account, but won't let the bid go through. I have checked everything there is to update on my account and it is updated. However it is telling me that I do not have a premium membership when I pay for an annual membership and clearly do or would not have a linden home. How do I get it resolved to place a bid on property?
