The method this.ComputeMetricsForUser must be called at least once before the final metrics can be computed

I have a problem that on my dataset after I have inserted the items, data and ratingactions the this.ComputeMetricsForUser error pops out. Although I have used the Samples from the source code and also the importing of the stuff is made similarly to the MovieLensDatasetMetrics project. Could somebody have any clue where the problem may be?

I solved it already, I created too large AllButN testset.
