\alpha_3, rather than \alpha_2 in the end
t_1 instead of t_1 t_2 in the brackets
\pi^2 -> \pi^{d/2}
there should be w_1,w_2,w_3, rather than r_1,r_2,r_3 at the axes
the 5th index stands for an irreducible numerator. Then the equality of -F(1,2,1,2,0) with the derivative of F(1,1,1,2,0) wrt M^2 should be taken into account. After an IBP reduction, one arrives at (6.68).
the factor 1/N! on the rhs should be omitted
