Sumerian: I don't know much about chess and programmes, but I don't think you need to back out of the tournament.
The tournament creator knew you were using the programme, and Fencer hasn't ruled it illegal so I would carry on as you are unless either person states otherwise.

I think this discussion should stay with the problem of how to handle the use of programmes (of all games, not just chess) in the rules. Are some programmes worse than others? Sumerian is using one he has wrote himself, therefore can only be as good as his own play. (I guess!)
Would it be ok for people to use their own programmes, but not shop bought, professional ones that have been created by masters? Or should it be absolutely none at all, under any circumstances?
