First time I'm doing this, is it that address where you sent the money you should use? I search on my address and found the token here: https://ethplorer.io/address/0xb5a5f22694352c15b00323844ad545abb2b11028 so isn't it that address at the top you should use? I don't know if I can try something that is wrong so wanted to check first what I should write.

-edit- Address in the link above 0xb5A5F22694352C15B00323844aD545ABb2B11028 worked

I think it's the gas limit that matters if you "get in" or not, the price or Gwei is just how fast you "get in" But seems he entered Gwei wrong 21000 instead of the normal 21 is insane! I had 21 Gwei and 300000 gas limit and "got in" with a total fee of 0.00598 Ether ($1,71). So I used about 290k gas and that guy had gas limit of 260k and ran out. Please feel free to correct me if this is wrong, just my own thinking.
