I'm not sure if this will help, but if you played it or downloaded it when you were logged into your account; you might be able to find it by looking through your "Things to rate" collection.
To find it, go to "My Library" by clicking on the little downwards arrow to the right of your username, at the top right of the page, it will be under "Explore".
Then on the left side of the screen, under "Library", look for "Things to rate", which will bring up "Things to rate and review". Maybe clicking on sort by "Oldest" might help?
