if you cant get the wallet to load, back up your wallet.dat and delete everything else.

Download the zip file to your desktop and run the syscoin wallet from the folder you unzipped, once the files are repopulated in your /Roaming/syscoin folder, copy over the wallet.dat and syscoin.conf file only using these nodes.

addnode=76.25.201.234:8369
addnode=67.253.247.113:8369
addnode=node.syscoin.me:6369


dont screw with any of the nodes in that huge list, just stick with those.  Make sure you delete everything and start over with your backed up wallet.dat

If you add that big list after you get synced up, you can lose your ability to load the wallet and have to start over.
