I had the same issues as above (entered credit card # for state return). I deleted the crash file -- opened the program back up. I unchecked the state return and was able to e-file my federal since no credit card option is needed. Will likely end up mailing my state return (as others, I already paid -- will call my credit card company to see if they can reverse the charges). It appears the credit card function is what is causing all the problems.
