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 BusinessBasics session.
Solution: You may be able to repair the file using the MYOB BusinessBasics Data Optimization Assistant. You can find the Optimization Assistant in the MYOB BusinessBasics folder that was created in the Windows Programs folder of your Start menu when you installed MYOB BusinessBasics. If you're able to optimize the file without further errors, we recommend that you then use the MYOB BusinessBasics 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 BusinessBasics 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 BusinessBasics. 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 a company file backup.
