I asked for a sample csv file but was told I needed BetS to use the form files. There is a free version of BetS available to do that.

The sample files provided were dbf files not csv. still usable in Excel.
I take it they were already processed by BetS which uses dbf data files.

If you are winning, then $55/M is not too bad, if losing, well any additional cost is an added burden.
