If the main solution solves, but the discrete frequency sweep fails then you may not have the license required to do a 'distributed solve' - where multiple frequencies are solved in parallel. - Go to the HPC settings, uncheck 'Auto-HPC', and make sure only 1 task is set. - Then re-run the frequency sweep. - It is also probably unnecessary (and will take a much longer time) to do a discrete sweep - choose interpolated sweep instead...
