Paypal does not recognize Cdn as Canadian Currency

[MaritimeLobsterExpress]

When my payments are sent to Paypal for processing the customer gets a message saying "this website does not accept this currency". I believe this is because virtuemart uses "CDN" for Canadian (as is displayed on invoices) but Paypal uses CAD so there is a mismatch.  Have any Canadian sellers run into this issue and how did you solve it?

Thanking you in advance for your help

This recipient does not accept payments denominated in CDN. Please contact the seller and ask him to update his payment receiving preferences to accept this currency.

This is the message that I am receiving.

Maybe it will be easier to change my currency to CAD. I tried to change the code but then Virtuemart does a conversion on the amounts. Any suggestions.
