There is an error in the log similar to this:
This error comes directly from the Intuit Software Development Kit (SDK) and indicates that tit is unable to recognize the requested file as being viable.
There are several possible reasons for this:
Attempt to open the file manually from where QQube synchronizes the data (if on a server, login as the special QQube synch user) and see if there are any errors. If you are unable to so, then contact QuickBooks technical support.
If you CAN open up the QB file manually, then attempt to run a Manual Synch choosing only the Company Setup/Preferences, while the file is open under the QB Admin user. If the log does not show "Success", then click on the link in the status column where the synch logs are listed in the QQube Configuration Tool.
If you get the same error, then remove the QB file from the QQube Configuration Tool, and, while logged in as Admin into QB, add the company back. And then try again.
Then repeat the same procedures Manually refreshing the Company Setup/Preferences. If you still get the same error, create a ticket in our support area using the 'Send to CLEARIFY Support' button.. and then comment in the ticket about what steps you have taken to correct this error.
