I have contacted Opera Support many times without response before I write here.

I'm using Opera Link on 2 Win PCs but from one day to the next without doing something all bookmarks, passwords etc. are lost.
On Opera Link website there is nothing. All data lost. Trash is empty, all is gone.

I want them back, there are years of Opera using, bookmarks, passwords and other stuff.

Can someone help me?

I have old backups of the wand.dat and other Oepra profile related files; but they are very old.
