We are very sorry to inform that Yahoo Finance have discontinued their API for exchange rates.
For Callista Currency Converter, this means that no new rates can be downloaded from Yahoo. The last downloaded rates will be used as long as Yahoo is your selected provider of rates.
Exchange rates from ECB will continue to work as before, but unfortunately only 36 currencies are offered by ECB. ECB can be selected as rates provider in Settings.
We are looking into the problem and are trying to find another trustworthy supplier of exchange rates. For the moment, we have no estimation on when this can be achieved.

More info about this can be found on Yahoo forums or directly using the following link:
