user129524: How to fix this?

My computer shut down without closing the program and now I try to help the network but cannot open the app... I'm a newbie, excuse myself please!

user125079: May you have corrupted files due to shutdown.                   I’ve suggest you to take a look at the debug.log file for further information. First try the -reindex option if you continue to have this issue there Remove the corrupted files and restart Bitcoin core again. Note: You should backup your wallet file before any operation.
