After display X Y data, exporting to shapefile creates bad data

Hi Folks,

I've got a fairly large tab delimited text file that I'm trying to work with. It's about 500 megabytes, and contains over 1.5 million records. After adding the data, the fields look fine, and I can add X Y data and it shows up correctly. However, I then export the data to a shapefile so that I can work with it, and the resulting shapefile has some fields shifted in their column, some columns are missing data entirely. It is no longer useful.

Is there anything in particular that I should be doing to ensure that this process works and the data is not useless at the end?
