Reject Code FW2-505-01 This Reject Code keeps popping up everytime I try to file my tax return. All info is correct, it has been revised several times. Any answers?

"For each of your W-2's, review the Employer ID Number (EIN) to ensure that it has been entered correctly. If necessary, contact the employer to make sure the Employer EIN is accurately reported on the W-2 that they issued." Is this the only way on to help fix the problem? What if I cannot contact the employer?
