When you say Gamelink cables, you mean the cables made by Monster right? I have a ton of monster stuff and they all have lifetime warranties to go along with them. I found this page on their site

You have to register your product there. The only tricky part is that you have to type in the last 6 digits of the UPC of the product. I think if you just go to a store and write that info down, since it is all the same anyways, then you should be able to register, and potentially get your cables replaced. Just a suggestion.
