Applying Precise Orbits (POD)

I‘m getting this error when I use the SNAP under "Radar–>Applying Precise Orbits (POD)"for the S-1 GRDs,

It sounds like maybe the orbit file zip files cannot be opened. Maybe it was stopped while downloading and you now have a corrupt partial zip file. Delete the orbit files and try again. It should download them again.

OK!Thank you for your help!
