QuickenBooks Upgrade to 2009 Pro...

Just upgraded from QuickBooks 2006 Pro to 2009 Pro.
After the upgrade, QuickBooks converts the data file so that it is compatable with the latest version (2009 Pro), and this process seemed to run fine.

Problem:
The main problem that I ran into after the upgrade was that QuickBooks 2009 Pro would crash when I would try to run the last bank reconciliation report (that was last done on the prior version).
I ran "Help->Update QuickBooks" to update the program, but it continued to crash when I would run the prior back reconciliation report.

Solution:
Then I found "File->Utilities->Rebuild Data". It required that you execute another backup. But, after the rebuild, QuickBooks 2009 Pro no-longer crashed when running the last bank reconciliation report.

So, if you are up against this problem of QuickBooks crashing after an upgrade.

1. Install QuickBooks 2009.
2. Use the "Help->Update QuickBooks" to update the program to its latest.
3. Let QuickBooks 2009 Pro update your data file to it's latest.
4. Run "File->Utilities->Rebuild Data" on the file to ensure that avoid the "crash on reporting bug".
