2 years missing

I understand your reasoning, however, I am talking about 2 years ago, not the previous year. I have been using MYOB for 15 or more years, so I know about financial year rollovers being a possible cause. The previous time I used the software was in June 2023 when I brought all my financial information up to date so that I would only have a few entries to carry out before winding up the year. When I started up Account Right to complete the year's work, there was a MYOB message about validating the file. It stopped me from opening the program. A call to MYOB and an emailed licence file resulted in what I said previously. The years 2020/21 and 2021/22 have all been completed at the appropriate times. The current year was set at June 2023. I've thought that a possible solution maybe to rollover the current "incorrect" year to 2022 and thence to 2023. I am unsure that if I do that, will I still have all my work from the 2022/23 year on the program?
