0000670: YaCy ver.1.90 doesn't start up.
I've been using YaCy for a long time.(ver.1.72 to 1.83)
Today, I tried the update it to ver. 1.90!
After pushing restart button, YaCy does'nt start up correctly.
So I tried to use it in the initial state.(Re-install YaCy)
However, YaCy can't still run... at all.
Download YaCy from the official site, and extract it.
Then execute 'startYACY.sh'.
