Yes - I've opened both of them without problems.
But I can't get rollouts to reproduce your game results - they
consistenly come in around these figures at 2 ply, it doesn't matter
whether I use huge 0 ply and no 1 ply or large 0 ply and large 1 ply.

2ply 1296 games - 0 ply filter accept 1 + 20 more at 0.25 equity
                  1 ply filter disabled:

win     win (g)  win (bg)  lose (g) lose (bg)   cubeless 
0.7166  0.3650   0.0885  -  0.0000   0.0000      0.8864
0.0154  0.0018   0.0013     0.0060   0.0000      0.0309

With the distribution 'normal' 2 ply filters, I get:
2 ply 1296 games - 

0.6773  0.3649   0.0911  -  0.0000   0.0000      0.8099
0.0154  0.0030   0.0021  -  0.0087   0.0000      0.0313

But something strikes me as very odd. For the above (normal filters),
I opened the rollout stats window:

        win single   win gammon     win bg   win single  win gammon  win bg
        player 0                             player 1
games      166           0             0         31         381      113
percent   12.81          0             0        2.39       29.4     8.72

Now those are odd figures for a 1296 game rollout, there are only 691
games accounted for. There are 53.32% of the results (643 games). And
the percentages don't match the rollout results window.
