Ouch, seems pretty serious. There is a way to restore character backups however - although you might have to do it for all your characters. This thread might help you: http://secretsofgrindea.com/forum/index.php?threads/gameplay-characters-gone.6290/

Figured I might hit the word cap for a post, so I split this one in two 
If you sort the files in the "Backups" folder by "Date Modified", you will be able to find the most recent backup of each character. This may be an an autosave or a regular save.

I might try to make a video on how to restore backups, seen as you're not the only one that's had some difficulty in the process. Would that be helpful?

I'm not amazingly proactive when it comes to videos, but I'm sure I'll get around to it at some point this or next week.
