When I was mining Nero, all my 970's done 55mh using the original and best version of the miner, which was the 1st version by Djm. 

Is there a bootstrap somewhere?

Solved 2 blocks so far with my Gigabyte 270oc - Running @ ~13.2Mhash/s.  Been a long time since I've gotten into the mining game. Up next I want to test out the 780ti.

Hashrate looks too low, i got this on HD6930
Try 14.9 driver DLLs

Yes I tried restart PC, also ran CCleaner just for case...nothing.
Stuck at Loading block index... message under oversized Nexus logo
Damm

There is an unfortunate issue in the BerkleeDB that is inclusive in this build, this could be due to your database being corrupted, so try to move your blkindex.dat and blk0001.dat into another folder in your nexus directory, to see if you can get it to boot that way. It can take some time to load up due to BerkleeDB's impressively inefficient database technology which will not exist in the future as I phase it out in light of my Lower Level Database I have been developing.

It usually is slow on its first start, if it boots you won't need to delete your .dat files, that will require you to resync, only necessary when db is corrupted. Otherwise I'll keep finishing up the LLD so that we can speed up the initialization process.

Thank You,

Release coming soon?
