Really having fun!
Playing so far, until League 1, Special Forces.
While on cutscene, (and cannot skip it to avoid that <i>fudge</i> error it's about to reach), until the part where, I see Nolan, and I added 2 Mercenaries to help me during the mission, then BOOM:
BoS.exe has stopped working. R6025 -Pure virtual function call.
WTF?

How to fix this?
Not even compatibility mode.
Not even setting graphics at it's lowest settings, and lowest resolution. X[
UPDATE (As of August 16, 2014):
Chose Mission, Special Forces, AFTER finishing Mission, CONVOY. Error R6025 occurs near end of cutscene.
Chose Mission, Special Forces, FIRST, BEFORE doing the other 2 missions: Strange, cutscene went very smoothly, and managed to gain control on Nolan.
Let me suspect: It's the guns, I purchased? In Convoy, I managed to get myself some sweet unlocked upgraded weapons, and finishing Convoy, prior to do, Special Forces. In Special Forces, Loadout section, the unlocked guns from Convoy, won't appear there.
Once, I'm finished with Special Forces, I hope I won't see R6025 when I play Convoy, after that previous mission and later on, the Nevada Desert Mission.
