Recently we have received the attached message approximately 1 week ago which popped up on opening the QB file.  A call was made to the phone number attached, [removed].  John answered who indicated that we have had a corrupted data file since April 2022 (it is now November.) We have not received this message previously and are working on the QB file from 2 different computers.  The QB file was installed on a new computer mid Oct and the company files were transferred to the new computer from a back-up of the data from the old computer.  No issue or message occurred on the new computer until last week (no message has occurred on the old computer). QB was deleted and reinstalled on the new computer as a double check.  John indicated that he could fix the corrupted data files, but I would need to purchase a plan which included their support services, for a subscription price of $1800./yr.  We performed a check in QB on both computers to verify if there were any corrupted data files and no data errors were found.  Has anyone else received the attached message and if yes, what are your thoughts.
