Hi Steve,
This was never really resolved from the Sample Data perspective.
Having completely re-installed my Adagio NFRs since then, I am still experiencing the same errors with my Sample Data.
What I have noticed is this: If I launch MC directly and tell it to use the ALwin MCsamdata, I get the above problems. Whereas if I launch AL and open the MCsamdata then use the Adagio menu to launch MC with the ALwin MCsamdata already open I do not get the above errors.
As for the demo, I used a copy of their data and their \ASP\MC*.* files on my laptop and everything went well - including the fact that the sale was made :-)
Regards, Pete
