Hi jam3zDlb,
checking plugin, option removed on one of updates ..
besides I never have such thing happened,
using 9600.17050.WINBLUE_REFRESH.140317-1640_X64FRE_ENTERPRISE_EVAL_EN-US-IR3_CENA_X64FREE_EN-US_DV9.ISO
for a long while now..
did you get Win8.1SE from here
http://win81se.cwcodes.net/Compressed/index.phpother than that, I have no idea, builds are made frequently by lots of people without trouble,
many builds made, nobody have such trouble, generally such things happens with undefault sources,
first try with default options, and see if it works ok on emulator,
later add other plugins one by one to see what cause this...
