We are using QB 2020 (Desktop Version) and recently lost all our data. Our Accountant, who filed our taxes last year in June 2020, had a copy which he emailed us. It has QBB extension. When we try to 'Restore a backup copy' the file that he has sent does not open. We are getting a warning message, "Sorry, only QuickBooks Accountant's Edition is able to open an Accountant's Copy file. Please use Accountant's Edition, or speak to you accountant, if you need to restore this file. 

My accountant is aware of this message and in fact has sent the right version of the file but we can't seem to get past this error/warning message. 

Does anyone know what we maybe doing wrong? 

Thanks!
