yes, blockchain reload with old Wallet
1. delete chain, NOT wallet.dat
or just starts the old wallet, then closing immediately.
and then start the new wallet, then runs, too!!
I can confirm thit method works on WinXP 32 bit.
Just exit from the old wallet before it connects to nodes, but after it created needed files in wallet directory.
Sync stucked on last day (about 900 blocks left), but after adding ypool to nodes, sync ended right. Command - addnode.
Nope, that method do not work right. After restarting the wallet, it lost some blocks, sync stuck on block 47696. After 3 minutes wallet crashes.
