Before starting the Validate & Repair process, you should copy your current data file within Quicken, and use that copied file in the validation process.
The Copy steps are:
1) Select: “File” > ”File Operations” > “Copy...”
2) In the Pop-Up make sure all info is correct and all boxes are checked, then click “OK”.
3) If the “Copy” process fails, it would likely be caused by a corrupt file. You can then try to bypass the corruption by holding down both the “Ctrl” and “Shift” Keys while performing step 1) immediately above.
4) If you are asked "Ignore errors that prevent file copy?" click on "Yes". (However you should know that doing this could cause data to be deleted.)
The “Validate & Repair” File steps are:
1) Select: “File” > ”File Operations” > “Validate and Repair...”
2) Make sure that the “File to validate and repair” is the new Copy you made above.
3) Read the “warnings” and check the boxes accordingly. (I suggest you click” “Validate file”, “Rebuild investing lots”, “Correct investing price history” and “Repair”)
4) Click “OK”
Once the Validate & Repair process finishes, review the output and correct any reported errors that the process did not repair.
Let me know how that goes.
