We have applied the security updates as suggested byEarly Impact, and everything except connecting to QuickBooks is working. Thisis what I have done based on what was suggested in the instructions:

"If you are using the ProductCart Synchronizer for QuickBooks,you will also need to update the SQL password in the he web.config file locatedin the QuickBooks directory."

I did this, along with changing the MS SQL username andpassword, changed the pcadmin directory to a different name, changed theusername and password for the ProductCart Control Panel, and the username andpassword to access the Windows server. All of these things were suggested aspart of the security update.
