those files are html browser based tool that you can run locally offline on your browser
ok, so I'll be using 19Fm1SKQnk8Gpy1v7fXyiHqvHiFPiTnFRF as destination address
current recommended tx fee is very very high close to 1000s/B 
so I set 0.00225 for tx fee which will be around ~850s/B ($36 @ $16,000) and 0.003 ($48) for tip if you don't mind
when you see and do this, hopefully the network fee will drop a few hundred nearing this weekend

Preparations:
- open this post so you can follow the step by step instruction easily
- have your private key for 1o4PtEAcNCHx8H5qU5R9XSGBMskJ2Jocp handy, my guess it starts with K or L
- go offline, disconnect your internet connection
- open your browser's private window so it doesn't cache, record or leave cookie, history, and etc
chrome incognito mode or firefox private window or whatever private browsing mode your browser have
- open the folder where you unzipped the two tools you've downloaded

First, acquiring your privkey:
- if the privkey you get from bc.info starts with 5 then you're set, jump to Second part
but if it starts with K or L, as I guessed before, then you need to find the real privkey for 1o4PtEAcN address
- open folder bitaddress.org-3.3.0 then click & drag bitaddress.org.html to new tab on your private browser
- you can move around your mouse to get to 100 % or just click "Wallet Details"
- enter your K or Lxxxx private key in the space provided and click "View Details"
- it should show your 1o4PtEAcNC... address on the left, scroll down a bit you can see "Private Key WIF" starts with a '5'
- the string starts with 5... is your actual private key for 1o4PtEAcNC...

Second, signing rawtx:
- open folder coinbin-1.3 then click & drag index.html to another new tab on your private browser
- click on menu "Sign" then copy paste your private key 5xxxx into the first input form
- also copy paste unsigned rawtx below into the second input form , and click submit
- it will give you "Signed transaction" , select and copy the new signed tx
- open notepad, paste this signed tx and save it for later use
- click on menu "Verify" and paste your signed tx in the input space provided then click submit
- make sure all inputs for your transactions are checkmarked on the signed column
- also double check the destination addresses and amounts are precisely as we agreed, 1Fq7XdaVC... is my address

Third, broadcast:
- close all incognito browser but don't forget to save the signed tx on your notepad txt file
- re-connect your internet and re-open your local coinb.in index.html or just go to live coinb.in page
- click on menu "Broadcast" and paste your signed tx here then click submit
- if it gives you error, you can broadcast/push it to other nodes or post here your signed tx
and I will help you push it to other available nodes

I hope these instructions clear enough for you to understand and follow
