Are you using SSME and SKSE 1.7.1? If yes, delete SSME! why? SKSE 1.7.1 already includes the mem patch by Sheson and using SSME and the SSME.ini possibly would cause CTDs. Delete all SSME-files and set your SKSE.ini to NMM
I don't understand "set your SKSE.ini to NMM?" Is this something that still needs to be done?
I hate ignoring install instructions.
