Efile Keeps getting Rejected

I use the desktop version of TT. My e-file has been rejected like 10 times and I don't know what's the problem. It started with not having a IRS issued IP Pin number. I thought it was the 5 digit number when you're filing but through the forum, I learned that it's a 6 digit number issued by the IRS. Both my wife and I got the pin number and we entered it in Personal/Other Tax Situations/Identify Protection Pin. It still got rejected. I double checked the prior AGI and it was correct. I've been e-filing for as long as I can remember but I'm at wit's end with this years filing. Any assistance would be greatly appreciated. Thanks!
