ok thk for burst. I've done what you say, but same error.
-download the minner with your link
-change the miner.conf with your post content
-change the HD path to G:\Burst\plots (because it was G:\Burst\plots) sorry, it don't take the two backslash
-lunch the miner
all is ok, but same error when found a block to mine.
if you can't do anything, it's not a problem, perhaps something wrong for me, but I really don't understand what :-)
so you've taked time for me, thk a lot, and if you can't do anything, it's not a problem. I'll try to find a solution and back to you ;-)
