Re: nDatalogSize not recognized
I opened it up and got the same error you are getting. It looks like you figured out the fix for that particular issue. (I think they just forgot to put "int" in front of nDatalogSize.) As for your problem of only being able to save good data the first time it's run, I'm afraid I can't help you there.
