Strange. Now I've checked it, and I get synced without problems
Have you deleted everything from ~/ambercoin/ directory (
EXCEPT wallet.dat)? Most important is to delete peers.dat file.
If no - do it.
Create an ambercoin.conf file there:
rpcuser=anyuser
rpcpassword=anypass
rpcallowip=127.0.0.*
gen=0
server=1
listen=1
addnode=37.59.21.199
addnode=78.8.2.228
addnode=85.10.194.50
or add this nodes by typing into the wallet console:
addnode 37.59.21.199 add
addnode 78.8.2.228 add
addnode 85.10.194.50 add
What OS do you use? Have you built the wallet yourself or used a precompiled one for Win or Mac OS X?
