Below are circumstances that can cause this error:
The 000000i.chk file may have been deleted from the directory. Either replace it in the UTSxx (where xx is the tax year of your program) directory or reinstall the software to restore this file.
An e-file/RAL acknowledgement may have been improperly renamed. Check the ACK and RAL directories for acknowledgements not named according to the 8.3 naming convention (eight characters-period-three characters) and rename them correctly.
The Wide List in the Print Acknowledgement window will allow you to see and print even improperly named acks. You must change Wide Form=0 to Wide Form=1 under the Acknowledgement Options heading in setup to change to the Wide List, as the Range Check Error prevents you from seeing this option in the Print Acknowledgement window.
There may have been a PDF attached to the return, but the attachment was either moved or renamed before the e-file was transmitted. To solve this problem, rename the attachment to the original name, move it back to the original location, or remove the attachment altogether.
The filename and EIN in the return may not match if you use the EIN to name the file. You can locate the problem return by erasing all e-files, opening each return, re-creating the e-file, and then attempting to transmit each one until you encounter this error message.
This information applies to all years of the UltimateTax software.
