I'm using that blockchain and everything's allright.
Try to add some nodes:
addnode=108.61.170.125
addnode=108.61.247.242
addnode=109.241.20.184
addnode=121.140.129.171
addnode=141.239.160.81
addnode=148.251.41.117
addnode=162.220.12.170
addnode=173.245.157.138
addnode=176.118.48.189
addnode=178.33.64.235
addnode=185.92.223.146
addnode=188.40.96.10
addnode=192.99.184.36
addnode=197.231.221.211
addnode=45.55.238.50
addnode=45.58.48.250
addnode=52.6.61.98
addnode=65.28.175.151
addnode=70.92.184.203
addnode=71.84.113.165
addnode=78.186.201.217
addnode=83.157.62.179
addnode=84.250.30.132
addnode=84.73.0.236
addnode=89.3.213.211
addnode=91.134.53.161

You can try to delete the peers.dat as well

And of course.......wait enough
