Did you use the correct spildle length for the crankset and seattube diameter? Did you disconnect the cable, back out the hi limit screw and check by hand that the derailer did indeed have insufficient throw? Did you start the derailer adjustment with chain on big cog and small ring with loose cable and about .5mm clearance between chain and inner plate, with shifter in small ring position? The derailer may be a bit out of spec for the crank,but that is unlikely the base issue.
