I get the same results in Mathematica v 8.0.4.0
$Version
"8.0 for Mac OS X x86 (64bit) (October 5, 2011)"
data = {{15000, 0.154}, {25000, 0.283}, {35000, 0.402}, {50000, 0.55}, {75000, 0.733}, {100000, 0.843}};
nlm01 = NonlinearModelFit[data, CDF[ParetoDistribution[khat, ahat], $x], {khat, ahat}, $x];
nlm01["BestFitParameters"]
{khat > 12989.3, ahat > 0.658768}
