Andy,
You can backup your accounts using the 'Backup Accounts...' option under the file menu at the top of the screen. Save your old data in a safe place, and then you can proceed to remove your old accounts and make new ones via the account menu at the top of the screen.
If you ordered CheckBook after Sept. 1st, 2006, you are eligible for a free upgrade to CheckBook Pro. If you ordered before then, you are still eligible for a 40 percent discount off the price of the 2.0 version of CheckBook or CheckBook Pro.
You can email us at
customerservice@splasm.com for more info. Thanks Andy!
