1. IMPORTANT !!!!! Backup your wallet.dat
2. Close wallet, if it does not close by itself, kill it with task manager
3. Go to %appdata%\lux and delete everything except wallet.dat
4. Downlaod and unzip this in the lux folder https://bootstrap.luxcore.io/bootstrap.zip
5. Download peers.dat (https://cdn.discordapp.com/attachments/416283023605235723/416283682865807370/peers.dat) and put it into %appdata%\lux
6. Start the wallet
7. It should start with "importing blocks from disk" while it searches for peers. This will take a few hours.

Thank you for the guide on syncing wallet. I remember that I have mined several LUXcoins, not much, and I have not upgraded my wallet so far behind current version. I almost used the second or third version of LUXcoin wallet. I have tried to open it but it can not be opened. Can I fix the problem and keep my coins, then transfer them to newest version of wallet safely, dev?
Thank you for your help if possible.
