Hmmm... If I copy and paste just dist = WeibullDistribution[7, 200]; data = RandomVariate[dist, 300]; ProbabilityScalePlot[data, "Weibull"] into a single cell then execute it, I see the error you reported. Alternatively, if I type the above by hand into a single cell I still see the error you reported consistently. Or I can copy each line one by one pasting each into a cell then execute each line before pasting the next and still get the error. But if I enter each line by hand into individual cells, I don't see the error. So, there appears to be a bug somewhere. That is, the various ways I've described above of doing the computation should all behave identically.
