Hi, I've been playing Sins & Sins Trinity for a few years, but always off line and (very) recently purchased Rebellion via eBay.

Box and contents are all there, but when registering for the Steam account, found that I'm unable to use the product code, shown on the booklet as it was previously registered by a previous owner.

I have contacted the seller, who is unable to help me, and I'm unable to see the subject in the FAQ's.

Is this an issue that can be solved?

Many thanks for any help you can offer.
