I don't even know what else to ask?! I even downloaded and re-installed the F4 4.4.14 from scratch, took your exact files for the EURUSD from post 409 and cannot reproduce the past results. Not even close.
I am using Strategy Tester 0.39 The only difference I could possibly think of is that I am compiling 32bit Win - but I cannot imagine this making any difference.
Trying the post 408 (original file settings - settings of A = 10 (GMT +1/+2), B = 130, C = 7 and D = 20. Stop at 40% of the daily ATR(20), ) I get this result:
Total trades: 3640
Longs: 1798 Shorts: 1842
Final balance: 385209.65$
Max DD: 45.25$
Max DD Length: 3315
PF: 1.05
R2: 0.98
Ulcer Index: 22.97
Time elapsed: 0:03:10.511000
It is similar with the other settings - e.g. post 428 (A=13 GMT +1/+2, B=150, C=3, D=8 with a 30% of the ATR(20) as a stoploss)
Total trades: 2400
Longs: 1413 Shorts: 987

Max DD: 48.09$
