Sarahann,

If you read the link you provided you will see the solution is the exact same I have been telling Intuit about for 2 years.  There is no need to provide more information, contact support, etc...you have the problem and solution right in front of you and it has been here for 2 YEARS!  Why Intuit refuses to fix a blatant bug that is crippling backup for all QuickBooks users I will never understand.

Read the problem and solution documented in painful details and let me know if you honestly do not get what the problem and solution are.
