nanopool ETN problem

[badkarma88]

I started mining ETN on nanopool using SMOS/Claymore XMR....everything works fine for about an hour then the hash rate drops to ZERO on all cards. I can restart everything and everything will work fine again for about an hour. I have mined ETN on some of the other pools without a problem and everything is rock steady, just cant get the bugs worked out on nanopool.

Any Ideas???
