There are no seednodes because the dev has abandoned the project which is a shame because of the abuse of jealous people on this thread by the looks of it.
I did try to fix it myself but do not have the skills time or resources but the windows masternode conf problem looks like an easy fix but I just cant get wallet to compile for win if anyone else wants to have a look maybe try
my fork on github or make your own from https://github.com/tocacyy/NeoDash.

If you still cant get your wallet to sync try these nodes from today add to your neodash.conf file.

addnode=185.221.152.25:7135
addnode=188.226.140.76:7135
addnode=31.134.146.184:7135
addnode=81.88.217.74:7135

Good luck to all who have time and money already in this project I hope somebody more skilled can takeover what looks to be a good little project or the orig dev can put what was said behind him and revive this young coin.
