I cant sync up the old classic wallets.
Tried it on two computers.
i also tried this config file:

rpcuser=username
rpcpassword=password
rpcallowip=127.0.0.1
server=1
daemon=1
rpcport=9334
listen=1
UpdatingLeaderboard=false
CPUMessage=Notified
suppressminingconsole=true
CPUMessage2=Notified
addnode=137.116.167.42
addnode=137.116.167.52
addnode=191.238.60.17
addnode=191.238.51.28
addnode=191.235.137.239
addnode=191.235.138.12
addnode=23.97.147.78
addnode=23.97.148.49
addnode=138.91.246.228
addnode=138.91.247.22
addnode=node.gridcoin.us
poolmining=false
cpumining=false
gpumining=false
suppressupgrade=true


It just gives me No block source available
I tried the new research client and it works and syncs up correctly.
Now i dont know how to exchange the coins, if old classic clients cant get synced then i cant send grc ,right?
