ID:210031 Checksum on line <number> does not match expected checksum

CAUSE: In the Convert Programming Files dialog box, you clicked Add File to add a Hexadecimal (Intel-Format) File (.hex) to either the Main Block Data item or the Bottom Boot Data item. However, the calculated checksum for the HEX File does not match the expected checksum for the HEX File. This error can occur when the HEX File is corrupted and cannot be used.

ACTION: Replace the HEX File with a HEX File that is not corrupted, or correct the error(s) in the HEX File.
