ELI5: How do I restore using backups?

[dtox_ftw]

Tried using PCSX-R which cause my machine to go buggy. So I forced restarted my machine and now when I try to open LaunchBox it says the file is corrupted and I need to try a backup file.

The backup files look to be .7z files, but don't actually open.   Not sure what the process is. Any help is appreciated.

If it is telling you which specific file is corrupted you can just open one of the backups zipped files and copy the specific xml to the \LaunchBox\Data folder. You can copy them all, but not needed if it tells you which one if corrupt.

Thank you for the quick reply. It looks like ALL the XML files were corrupt.  Also, I was confused because my latest backup wasn't opening but thats because that was corrupt too. 

Going back to an earlier version got me all the XMLs that I needed. Thanks.
