Trouble reading in txt file. Only want to read in certain columns.

Hi Everyone,
I need to be able to read in 1 to 5 very large data files that are stored as *.txt files. I used the record macro feature to make the following macro. I basically used the open feature and deactivated all of the columns except the two I wanted. It works when I do it manually, but when I try to play back the macro, I get an "out of memory message". Anyone know why that is, and does anyone know of a better way to do what I want?
Thanks
Edward
