Download the latest client,but out of sync,how to deal with it?
TKS.
Check connection.
Add blockexplorer as node:
addnode=
66.228.60.13(Edit file: stablecoin.conf)
Sorry for my stupid question.
What to type in stablecoin.conf file and how to addnode? any detailed infor?
Thank you
No stupid questions, we all need to learn

Just create the stablecoin.conf file (if you don't have one, if you do just add the extra line in the file) and in the file add the line posted above, exactly as it is:
addnode=66.228.60.13
Adding this line of text will do all you need. Make sure to restart the wallet after you've modified the conf file.
