Have you downloaded the new beta wallet?
Are you on windows? If you can't wait, heres the new unstable (beta) wallet with new checkpoints.
As with the previous beta versions if you crash the wallet you will need to delete the C:/programdata/boost_interprocess folder before starting the wallet again).
Just redownload the wallet to be safe. I chose a new checkpoint.
If you want to be super safe you can delete everything but the wallet/.conf (blockchain is so small it takes 20s to download anyway).
I've included a file DeleteBlockchain.bat which will automatically delete the blockchain files for you without harming your wallet.
Just double click it before opening the new wallet and you are good to go.
You can right click the .bat file and select edit to see what it contains:
C:
del /F /Q %UserProfile%\AppData\Roaming\PreminePlus\database\
del /F /Q %UserProfile%\AppData\Roaming\PreminePlus\.lock
del /F /Q %UserProfile%\AppData\Roaming\PreminePlus\blk0001.dat
del /F /Q %UserProfile%\AppData\Roaming\PreminePlus\blkindex.dat
del /F /Q %UserProfile%\AppData\Roaming\PreminePlus\db.log
del /F /Q %UserProfile%\AppData\Roaming\PreminePlus\debug.log
del /F /Q %UserProfile%\AppData\Roaming\PreminePlus\peers.dat
pause
Will have those stable wallets for the rest of you guys soon.
Don't forget to delete your blockchain or run the .bat file I've included.
You won't see your quiz rewards until you've updated.
If you really want them for whatever reason, to stake or whatever then use the beta wallet for now.
I'm going to be making an announcement about the changes soon and I'll be including the stable wallet then.
