Rejected e-file

I submitted my taxes by E-file.  They were rejected and the reasons given were, the AGI was incorrect or the Pin # didn't match last year.  I had not E-filed last year.  So, when everything seemed to check I got concerned and printed them and mailed them in.  Then I got a notice of a Critical reminder to resubmit my e-file.  My question is, have I really messed things up of can this be corrected?  Thank You
