My guess is a fresh install was needed instead of editing scorpio.ini.
Hi Daniel,
I made a fresh install with install.bat and then I edited the scorpio.ini for the use with NN 42850. I started 1 times scorpio in command line window and then inside the gui. Here is my scorpio ini:

# montecarlo - Use montecarlo tree search (MCTS) if set to 1
# treeht - Maximum size of tree to store in memory given in MB.
# Note that this memory is not allocated at start up; it only
# specifies the maximum limit the tree could grow to.
# Note: Don't think you are making scorpio weak by not setting
# this memory to high value, infact treeht=0 is the strongest
# MCTS setting.
# frac_freeze_tree [0 - 100] - freeze tree after this percentage of time is spent
# frac_alphabeta [0 - 100] - use alpha-beta search this percent of the time
# frac_abrollouts [0 - 100] - use alpha-beta rollouts search this percent of the time
# mcts_strategy_depth [0 - 64] - Lookahead depth for MCTS rollouts
# alphabeta_depth [0 - 64] - Fixed search depth for standard alphabeta searches at the leaves
# evaluate_depth [-4 - 64] - Fixed search depth for evaluation of new children during expansion
# (-4=eval,-3=see,-2=recap qsearch,-1=no-checks qsearch 0=qsearch,x=search)
# backup_type [0 - 7] - minmax = 0, averaging = 1, mixed = 2, for mixing score with
# previous ID use 3,4,5 resp. 6 is classic MCTS, 7 is mixing by visit count
# reuse_tree - reuse MCTS tree between moves
# virtual_loss - virtual loss for parallel search
# visit_threshold - minimum number of visits for minimax backup

# cpuct_init - Starting cpuct value
# cpuct_base - Denominator of cpuct forumula
# fpu_is_loss - FPU is loss (1=true, 0=false)
