AbleCommerce Shopping Cart Software

Hi,
I have been assigned with the task to do the Exchange Rate Update for the currencies. When i run the process on on my stage server I am getting an error as shown below.
"Exchange rate update for Euro failed Cannot convert from USD to CAD.Parameter name: sourceCurrency"
Is something wrong with the dll that we are using?I am struck with this issue for a long time. Please help.

Thanks!!!!!!!

What version of AC7 are you using?

Have you tried switching to a different provider using the dropdown at the bottom to see if the problem still occurs?

Maybe post some screenshots of your Currency page would help us too.
