Problems with my GED in minnesota?

Back in 2003 I took my GED testing, I had failed one, but then retook it, and I was told I passed and got a copy of my ged and everything. Did the whole walk thing and was really proud of myself.

Now, 7 years later, I needed a copy of that ((my first one is to far from me, in another state)) I started digging around and find out that the second test I took was the same as the first one so I never passed it.

My question is, how could they do that? Should I call a lawyer or something?

In the last 7 years I was never told that I never passed, and I wouldn't have ever found out if I didn't need this second copy.
