For all wallet sync issues:
Until that point though, there will be syncing issues.
To troubleshoot these issues, first try restarting your wallet. This will reset any stale connections the wallet may have made to a server that has recently gone down from an attack.
If that doesn't work, try adding the addnodes to the conf specified above by gjhigginis (thank you btw) and restart your wallet.
If that doesn't work, step away for 15m and come back to it after letting it run for that time frame. The wallet may need a few minutes to establish connections to the network.
When all of those steps have failed, please join our slack for immediate attention and correspondence. Post your email address here in the thread, in a PM to me or any SCSY dev account, or email me at [email protected] IF you need immediate assistance
If the steps above do not work, there is another advanced procedure you can do to re-download the blockchain from the network. This has proven to help some sync issues that weren't able to be fixed by anything else BUT you should back up your wallet first. Which ever method you use to back it up, do it before proceeding with this procedure.
To do this, on a windows computer, you need to be able to see hidden files/directories on your machine. Follow the link below to see how to do this: (If you already are able to do this, skip this step)
http://windows.microsoft.com/en-us/windows/show-hidden-files#show-hidden-files=windows-7
After you are able to see the hidden files/folders of your windows machine, open windows explorer (not internet explorer) and navigate to your AppData directory (C:/Users/whateverYourUserNameIs/AppData/Roaming/securitycoin/)
Once there, you will see a bunch of files and folders, one of which being your 'wallet.dat' files (super, super important) and your 'securitycoin.conf' file (kinda important, mostly to our advanced users).
To redownload the blockchain, you want to delete everything in this AppData directoryEXCEPT THE 'wallet.dat' AND THE 'securitycoin.conf' FILES
Once the files and folders are deleted, restart your wallet. Should be good and start syncing.
Sorry again for the issues everybody, we're on the case and discussing solutions to these issues.
I don't know how to be more clear about that lol as you will lose your coins if you do delete it.
