Today i loss 47% Hashrate. Why?

Hi everybody.-

I was mining about two weeks ago and all its ok. no problems. Yesterday i saw in “hiveon” the worker Offline, so i upgrade the software to 0.6-192@210111. and restart the miner, but keep the problem. so restart the engine and nothing. i wrote to suport team and them told me that

“There are interruptions in the display of statistics. This does not affect mining. Soon your statistics will be displayed.”

but now… i saw it and Hashrate is too low… Why?
