My MathCad document stopped working with this error message, and I cannot get it working again. I have attached the document here, and a picture of the error message. What can I do to make it work again?
The symbolic evaluation of the root function damaging the symbolic engine (muPad) sure is a bug.
Solution is to delete the symbolic evaluations of the root functions, save the worksheet, close Prime and start it again. I guess you won't need a symbolic evaluation, right?
