I am on Win 10 PRO 64 bit too, Cinema 4D studio R17 and R18, tried with no plugins at all except for SurfaceSpread, without the Prefernces folder, without my default new.c4d scene, on both releases and on 3 different PC (2 DELLs and 1 HP with fresh instlalls done only for testing SS)... no luck at all... The plugin works perfectly on my iMAC with a 1000x1000 segments terrain but becomes unresponsive at 500x250 on the various Win 10 machines I've used for testing and the main one where I have Cinema 4D installed onto. Any idea of what may be causing my issue?
Thanks in any case for your answer Icecaveman!
