EncPreauth returning Cancelled: null

Hello, i'm using the exact example here https://github.com/Moneris/eCommerce-Unified-API-dotNet/blob/master/Examples/CA/TestCanadaEncPreauth.cs without changing anything. Here's the result:

CardType = null
TransAmount = null
TxnNumber = null
ReceiptId = null
TransType = null
ReferenceNum = null
ResponseCode = null
BankTotals =
Message = Cancelled: null
AuthCode = null
Complete = false
TransDate = null
TransTime = null
Ticket = null
TimedOut = false
CardLevelResult =
MaskedPan =

I tried it with dll version 1.0.10 and 1.0.24.

Can I get help as to why this is not working?

Thank you!
