Maybe you are not estimating the same model -- one may have an intercept, and the other doesn't. Or maybe something happens while you read the data -- start by comparing summary statistics, tabulations and plots of your data.

But as you didn't tell what you estimated, and how, it is a tad hard for use to guess. There is a Posting Guide recommending how to phrase questions and what to suplly ...
