The wallet windows is not synchronized with the network
you should add nodes.
if you dont know how to, heres a guide:
find your wallet location. locate a file called vivoinnovaonexgobyted.conf. open that file and add:
addnode=199.247.26.251:9910
addnode=72.245.10.219:9910
addnode=23.95.60.236:9910
addnode=185.203.242.19:9910
addnode=176.114.6.16:9910
addnode=94.242.199.95:9910
addnode=23.95.216.61:9910
addnode=23.95.216.72:9910
addnode=198.23.207.222:9910
addnode=72.245.10.220:9910
save the file and restart your wallet. now it should sync!
