Hi,
I have the same problems, it mine for two or three minutes and then it crash with this error.
And also the maximum usage of my cpu reach at top the 30% of it, no mater how many core I set (of course over 1/3 of them). Any clue?
miner is experimental in order to fix that just go to %appdata% click on the file RBX and delete all but Rubix.dat and RuBiX.conf once fixed don't use miner, just stake. we'll make a version without the miner as soon as we finish the development of an Optimized CPU miner and a Nvidia GPU miner.
