I was trying to import games and every game but 1 was erased. Do you know how to retrieve that data?

Not sure what you mean by you were trying to "import games". Where were you importing them from? Did you use the Options -> Import option, and read the message that pops up saying it is going to overwrite your data, and still enter YES to continue? If that is the case, then you have overwritten your data as the import screen says. If you have used iScorecast, then your games will still exist on our server and you will be able to recover them. Send us an email to support@iscoresports.com with your Customer ID and we can take a look at your data.

Do I put any reference number to the email or just explain it again?

Just copy / paste your original message from above and we can take a look.
