To help you, we need to understand what kind of error has happened in the system. Email a screenshot of the error to firstname.lastname@example.org with the description of the problem. We will contact you as soon as possible.
If an error occurs in the particular hand, please attach to your letter the file with the hand history text.
Use the function "Share this result" on the Calculate results screen when possible, so we can see the exact hand or situation where the problem occurred.
