Try the attached version of the CSV Import.
A couple things to note…
1. It doesn’t have the code to support importing IM and social media yet, but this shouldn’t impact the data you’re importing.
2. Make sure you triple check your mapping before you click that import button. There is not a chance to confirm. I think I would even suggest importing only 5 in the first round just to make sure everything looks as expected, then import the remainder.
