My counter crashed while staking orbitcoin. When I try to launch the wallet it program crashes while trying to load blocks. Is there a way to recover my wallet or did I just lose all my coins?
Rebuild the block index and other data bases by launching your wallet with -reindex
If it doesn't help, then it must be a very hard crash which damaged some parts of the block chain stored. Make a copy of your wallet.dat and orbitcoin.conf if you have any, delete your data directory, download and extract .orbitcoin.tar.xz from the OP, put wallet.dat and orbitcoin.conf back in place.
-reindex worked like a charm.
