As long as you started with the correct stringing pattern, it should be solvable if the rings are connected on the front with all the colours consistent. Here is a picture, although small. If you can't solve it, you probably strung it starting with the wrong pattern (I think you start with D but I could be wrong).
Really I need a picture of the back because there are 2 pairs of identical tiles if you look at hte front face. thanks anyway.
