Hi there,

This can be caused by:
Shortcuts on the icon bars to features that are no longer in the product such as the Open PO List
Damaged Admin user password
Damaged Users

How to fix the problem:
Remove the offending shortcuts
Change the Admin user password
Delete all users but the Admin user

Detailed Instructions:

In the original version of QuickBooks (the one you are converting from):

To remove shortcuts from the Icon Bar:
Login as one of your users
Click on View>Customize Icon Bar
Click the Open PO List under the Icon bar Content
Click the Delete button
With each user follow steps 1-5 until none have the Open PO List as a shortcut.

If you continue to get this message, there may be other shortcuts causing the problem as well. You can remove all the shortcuts from the icon bar and set them up again later.

To change the Admin user password:
Log in as the Admin user
Click on Company>Set Up Users and Passwords>Change your password

To delete all users but the Admin user:
Log in as the Admin user
Click on Company>Set Up Users and Passwords>Set up Users
On the User List, click on each user that is not the (Admin User) one at a time
Click Delete User

Good Luck!!
Thanks
