You are right that black is lost after 62...d3  63.Ne4 but I think that
Fritz5.32 will play 63.Kf8(I do not know because I do no have Fritz5.32 but at
least Fritz5.16 cannot find 63.Kf8 in 15 minutes on my pentium200MMX.

and fritz is closer than Junior or chessmaster to understanding that the KPPPvs
KPP is a draw.
It evaluates this only as 1.xx and not as 2.xx pawns advantage for white.
