Custom Audience CSV problem

I'm going out of my mind with this so I'm hoping someone can help. I'm new to marketing and want to do a targeted Facebook ad campaign. I bought Social Leads Freak and a Graph Scraper app. Using SLF I built up a really nice, really strong targeted list of uIDs at about a million of people who "Like" and are involved in gun rights FB pages and communities.

I exported the Ids into CSV files then combined the CSV files into one nice neat one.

When I download the CSV from Social Leads Freak and open it in Excel it displays like this:

CELL: 1.00007E+14

Then, on the top next to "fx" it shows: 100000440017064

This file doesn't even upload to Facebook -- it doesn't allow it. Then I noticed that the number format was under "General" so I switched it to "number", which displayed as the following:

100000440017064.00

This wouldn't upload either so I deleted all the ".00″ from them. It still wouldn't upload.

So I saved two versions of text, "Unicode" and then "Tab Delimited." These DID upload. However, Facebook ads rejects all ads with a custom audience containing the file.

So, basically, the ad WITHOUT the custom audience included is always approved. As soon as I add it, it's rejected.

I think it has something to do with the format in which I am doing it. Would anybody be willing to perhaps take a look at the file itself and let me know?
