I have installed currency_rate_update module and trying to update EUR,USD,COP currencies.

I am using European central bank services.  While running cron job, giving error "Unsupported currency COP" error. If i remove COP from the currencies list then it's updating well. So i would come to know European central bank service can't update "COP" currency. I have change the service to "bank of canada", this also raising an error "Exchange data format error for Bank of Canada - EUR. Please check provider data format and/or source code. " Can any one please tell me the solution for this. My base currency is USD and company currency is USD.
