Okay, I know what the problem is, the links go to the files as follows:
aolserver-3.3.1+ad13-1.i386.rpm
aolserver-nsfts-3.3.1+ad13-1.i386.rpm
aolserver-nsxml-3.3.1+ad13-1.i386.rpm
and should go to:
aolserver-3.3.1-1+ad13.i386.rpm
aolserver-nsfts-3.3.1-1+ad13.i386.rpm
aolserver-nsxml-3.3.1-1+ad13.i386.rpm
The "-1" is in the wrong place...
