1) In your exec associate command you should not prefix your username with "wcg_".  It should just be your wcg username.
2) Your WCG web account username should not have an e-mail suffix.  It should just be ksuny for example not ksuny@gmail.com.
3) After you make a change in WCG, you must wait about 12 hours to see the changes propagate.  Then try to exec associate again.
4) Id like to see the results of exec associate pasted.  None of the screen shots take that output to show.
5) I think we do have a faucet error on web.biblepay.org, but first lets confirm you are associated and in the chain, and then paste your cpid here *after* all that is working.
