Xtracta Status 403

When opening Xtracta to repair exceptions and after repairing several I am unable to open any further to repair without getting this message:

<documents_response>

<Status>403</status>

<message>Document is not in valid status to open (pre-processing)>/message>

Solution

This is because the 10 free invoices have been used up.  The 403 status means that the user is not authorised to access any further invoices.

 How many Xtracta Invoices Do I have left will let the user know when the plan renews.
