I still can't reproduce an error identical to yours, but I managed to reproduce a very similar one.
It occurs when you have calculated in a specific currency and then deleted that currency from Administration > Currency.

In my case, the error was resolved when I restored the deleted currency in Administration > Currency. You can try. If it doesn't help, then you need more details and screenshots.
