I just started mining this ,every share is getting rejected for being above target ,what is this?
You need to download the vertcoin miner. You will need to set thread concurrency at about 60% of what you normally use. And keep an eye out for hardware errors. If you are getting them, lower intensity until it is no longer an issue.
I hope this solves your problem!
Thanks for helping out, you beat me to it. :-)
