like some other person also said after 1.4.1 version there is a bug with paymentid.worker/pass syntax .
/* Address of you wallet */
"wallet" : "ExchangeXmrDepositwalletadress.PaymentID.workername/nanopoolpasswordforjsonsettings",
The above configuration is working with version 1.3.1..No problem.
But same config.txt file with same start.bat file in version 1.4.1 (just working start.bat and working config.txt is copied to 1.4.1 folder)..--> NO HASH on nanopool (today I left opened 6 hours and mined for nothing, shares found in srbminer but , hash on nanopool and balance 0 = zero ! )
you must set your wallet adress in pools.txt not in config

Thank you mate, from Doc`s answer below, I would lost one more day , if you didnt mention it is in POOLS.TXT file..There was no pools.txt file in 1.3.1 ..Anyway 6 hours of Vegafrontier Editons to DOc`s wallet in pools.txt, i hope I am no more greddybas* afterall
How do I need to enter email address for nanopool notification, where exactly? In the password field password: x:mail... or address.worker/email?
From nanopool:
