To add to Ed's comments:
Find someone in the immediate department/area to walk you through your first structure. But to answer your question: What about the MR didn't work? Use your MR model to find your heavy atoms. They can be found using anomalous data difference fouriers (or even better log likelihood gradient maps) using data as low as 6-8A, and, in my case, using a model that was about 50% (mass) of the ASU with the placement of that 50% to be about 80-90% correct.
