Well we need a lot more information in order to be able to help you.
Here are some things to check:
- How are you locating your data? If coordinates, are they correct (correct signs, no zeroes, etc). If street addresses, again are they correct?
- Do you have your location columns set correctly? For example are you accidentally importing street addresses as just zipcodes? (this would result in multiple pushpins appearing at the same locations - the zipcode centroids)
- Which version of MapPoint are you using? Newer versions have more accurate road data
- Does it tell you that it cannot locate the locations? Have a look at these locations.
