Situation
This message may appear when you try to open a company file. It indicates that the company file was damaged in a prior MYOB Premier Accounting session.
Solution
You may be able to repair the file using the MYOB Premier Accounting Data Optimization Assistant. You can find the Optimization Assistant in the MYOB Premier Accounting folder that was created in the Windows Programs folder of your Start menu when you installed MYOB Premier Accounting.
If you're able to optimize the file without further errors, we recommend that you then use the MYOB Premier Accounting Data Verification Utility to be sure your company file is in its "healthiest" form. You can find the Verify Company File command under the MYOB Premier Accounting File menu.
If the Optimization Assistant or the Data Verification Utility indicates that the problem can't be repaired, you'll need to restore your most recent backup to continue working in MYOB Premier Accounting. Regrettably, any entries that you made since the most recent backup will need to be reentered. To learn more about restoring a backup of your company file see Restoring company files.
