Got datalogger

Finally got my Palm datalogger. From playing with it as driving to/from work today, it looks cool. I got mine off ebay, so god only knows what I'm missing. Got a couple questions.

1) There's a program called Palm n Stein. It always causes my device to have a fatal error and rest, even when connected to the car. Whys that?

2) ODBGauge looks pretty sweet. Is there anyway to go back and look at the graphs? I recorded a run, and then tried to download to PC and it didn't do anything. Any help?

3) Is that all that comes with the datalogger? Am I missing anything else? Thanks

Also, is there any other software (prefferably freeware) that will help too?

And, can I get the real datalogger from DIgital Tuning without having to buy the cable too? I just need software.
