Delete all from %appdata%\Snowgem (except wallet.dat & snowgem.conf) then launch snowgemd.exe
tried that way several times, but sync stopping at 12% due to 0 connection (win v1.0.6c)
what am i doing wrong?

As of today, add following to your .conf file to sync:
port=16113
addnode=45.76.111.3
addnode=45.76.137.106
addnode=45.32.79.163
addnode=207.246.67.167
addnode=45.77.70.230
addnode=45.77.160.169
addnode=104.238.149.197
addnode=207.148.68.108
addnode=104.24.117.245
