Can confirm the wallet is stuck on Windows 7. This is not an isolated Windows 8/8.1 issue.
The full blockchain needs uploading, or we are all going to be stuck syncing!
but it crashed only if no chain is available
and after they close and open again, you do not get it sync
Did all from above in this topic.., add nodelist in config, old wallet / current wallet, remove blockchain db (it crashes NRS at start), win7 - win 8/8.1. Stuck at block: blocks" : 47598.
