History and Bookmark System not functional

Hello, my name is Edward. I fully need help. I had no problems using comodo dragon, but just last few months ago, all of a sudden when I started my computer and used comodo dragon, all my history and bookmarks have disappeared. And a message that says “History and bookmark system is not functional” message is appearing. I tried to restore it from backup and it says “Unable to process backup file”. I don’t know what to do. Anyone please help?

Hello CrystalV,

Thank you for reporting.Informed to corresponding team and they will check that.
Have a nice day!

Kind Regards,

Hello Edward, can you please make a print screen of the error and where it pop’s up, do you have a back-up doc for the bookmarks?
