Allure Flooring

I have the adhesive Allure for about 4 years now. I am very disappointed as it is separating at the short seams. It is pulling apart and leaving a ugly gap on many (not all) of the short seams. Last year I cut some small strips and laid them in the openings and now they have pulled even further apart. I thought it had something to do with the extreme cold we have here, so last winter I kept the MH warm with space heaters while in storage. In the spring I noticed that the gaps hadn't grown larger, but recently they have been opening up more. I need to find my receipt and go back to Home Depot but I'm afraid they won't warrantee because it was installed in a MH instead of a house.
Wish me luck!
