Error Opening Company.asd

"The message 'Error Opening Company.asd' was encountered when displaying an Aatrix tax form."

Solution (1):  This error indicates that the Federal Tax ID stored in the Payroll > W2s > Properties screen and/or the ID stored in the Payables > Accounts Payables Reports > 1099s > Properties screen do not match the Federal Tax ID stored in the File > System Administrator > Configuration > Accounting Tab screen.

Solution (2):  This error can also be caused by changing the Federal Tax ID after using Aatrix with a different tax ID.  Rename the Aatrix Folder that is found in the Company Folder.
