I'm trying to do MOAC 70-620 labs but it keeps coming up as "Error 1015 \nUnknown Error". I can do all the exercises but cannot launch the labs. This \nis affecting all members of my class. I have tried it on both my laptop and \non my desktop with the same results. The school has contacted Microsoft and \nrecieved the typical "We'll get back to you". We are all getting way behind \nbecause of this issue, any help is appreciated. Thanks in advance.
