Hi,
everything works fine with FC5.2 under Mathematica 5.2.
It might or might not work under Mathematica 4.x
Please upgrade to Mathematica 5.2.

In[2]:= $FeynCalcVersion

Out[2]= 5.2

In[3]:= ScalarProduct[p, p] = 0;

In[4]:= Tr[GAD[a].GSD[p].GAD[b].GSD[p]] //FCE //InputForm

Out[4]//InputForm= 8*FVD[p, a]*FVD[p, b]

Regards,
Rolf
