OK. The only thing that is different between 4.0 and 4.1 was that fact the I renamed UnitParts10688i.upc to UnitParts8688i.upc. That negated a conflict between the Gato conning and the 688i Sail. Hadn't heard of it causing a crash before but that doesn't mean it wouldn't I guess. But glad to hear it's working for you now!
