William, change the adress of the FTP site in line 61 urlwrite to:
'ftp://software.seg.org/pub/datasets/2D/2004_BP_Vel_Benchmark/'
This should solve the issue.
setup.m fails with the following errors:
??? Error using ==> urlwrite at 140
Error downloading URL. Your network connection may be down or your proxy settings improperly
configured.
Error in ==> setup at 61
urlwrite(['ftp://seismic.seg.org/pub/datasets/2D/2004_BP_Vel_Benchmark/',f{i}],f{i});

This is using MATLAB 7.12.0 (R2011a).
