I went to open my wallet and it said "error building data base,
do you want to re-build?(or something along those lines), I said yes, (Duhhh!) then it just shut down. Tried re booting it,
the splash screen appeared momentarily then shut down. Tried again, no good, just shut down after splash screen.
Anyway,deleted , reinstalled re-synched (wow so fast!! very impressive!) then shut down, replaced the virgin wallet dat file (empty of course)
with my backed up wallet dat file, re booted and bingo, all good, correct balance...baking and staking.
Only mention this as this never happened to me on last version (or any wallet ftm). Maybe a bug in new version?
Or it could have been an event on my pc that may have corrupted a file as I had a brief power outage last week that
shut down all my miners and pcs.
Anyway just thought Id pass that along to community in case anyone else had same issue.
I have had exactly the same happen after a crash, error message, and then after that wallet wouldn't start anymore until I deleted everything except the wallet.
As you say, good thing the sync is fast...
