Yes, at times the road does seem very long, especially when using third party .NET components and the manual only has C#/VB code and not Progress examples. It can sometimes involve a lot of trail and error to obtain the Progress code.
Error 5638 basically means that oneSage.SDK.RD.Data.SageStart.AccountRow does not exist as a class in oneSage.SDK. If you do a quick search for AccountRow in the manual it is not found which suggests it does not exist as a class, property or method.
Where did you get the C# code from that has this line?:
It is referencing AccountRow which appears not to exist
