Update,
This is a Mandatory upgrade to the Aero Wallet,
Just to make it clear you should install the new Aero wallet (Aero-QT Win-Fix https://mega.co.nz/#!VoMAwBTS!TiQLAdo2YoqnPG4MDDy71gJfaXkPY3mmFmVEPYIDNfQ)
You must shut down your old wallet.
Also please delete the old wallet (keep wallet.dat).
Download and install the new wallet.
Then finally Resync your new wallet.
This is how we fix the situation in the fastest possible way!
Thank you,
Majika Idol, that's exactly what I've done.
So, first I didn't have any problem.
Then, I saw this post saying that it is a mandatory update.
So, I did exactly what is mentionned there and it doesn't work.
Don't worry. What you've described is to be expected. The old blockchain gotta die before your wallet can sync correctly.
