I'm running into the following error when I try to open my wallet:
Runaway Exception
A fatal error occurred. MintCoin can no longer continue safely and will quit.
Exception: St13runtime_error
CDB(): error opening database environment IO error...
I'm running Windows10. Any ideas on what I can do to fix this?
Do you have any more detail? Do you have a debug log? What wallet version are you running?
I started it up this morning and it seems to be working now even though I tried repeatedly last night with the same result. That's a first. Apparently it somehow healed itself. Anyway, I'm running wallet version 2.0.2.0
Thanks for your response anyway.
Other coins including bitcoin give the same error. Peter Wuille (a bitcoin core developer) recommends restarting a wallet with the -reindex option to fix it in this stackexchange thread.
