Sage CRM Currency Rates Add On Not Working

Hi All,

Experiencing a problem with the Currency Rates Add on.

Was working perfectly, No changes to the environment.

but now returns a Server Error - 500 - Internal Server Error when i try to Update Rates.

Reinstalled the component and still the same.

The MoneyConverter.com has discontinued RSS Feeds, could this also affect it?

Possible solutions?

thanks
