with New Native C++ Miner Update 1.0 R3 for some plots I get following info, e.g.
plot read done. acc#_4000001_80000_80000
0 noncesis this actually ok or are these plots fckd up?

are you mining while generating plot? or generating is done?
a while ago, i did mining while generating it shows 0 nonce, and then i restart the miner, then it read the nonces, and then its no problem generating while mining.
and also check if the miner has read access to the file, maybe try with administrator priviledge first
