Look into the log file from Claymore Miner and post the last lines here.
And please give us more information. Cards, Driver version, which OS and so on. We have no glass sphere.
wrong board, but i can't not answer a mining related question
do the following
1- configure the bat file to this code
EthDcrMiner64.exe -epool eth-us-east1.nanopool.org:9999 -ewal 0xd3a9b641986cd95b3ccd71e246e2e1ada5349c3b.rig1/vahpourvisuals@gmail.com -epsw x -mode 1
2- ensure the EthDcrMiner64.exe and the start.bat are on the same folder if not then it's not going to work.
let me now how it goes, if you face any further issues , post away, if i take too long to reply (24hrs or more ) feel free to send a pm.
Good luck.
1. your command line is the same like the one from vahpour, you only delete the -ftime command, so why should this one work better?
2. Claymore starts, he postet the first lines, so your second point is clear
