Sorry, all sales are final, per the terms you
agreed to at the time of the sale. It's very important that you try all
the different settings that can be changed within the client, to see
what yields you the best quality of data. You can preview the data, and
even save a file here and there, to see what gives you the best
results. Don't use the bulk of your quota until you're happy with the
results of the VirtualLab file search.
