I always get this crap when I launch byteball, anyone has any ideas?

I had a newer version of NW.js but I removed it and I still see this.
I am using the latest version (1.10.1).
Make a backup and do this:
Linux users who upgrade from 1.10.0 will have to delete all files (but not subdirectories!) in ~/.config/byteball/Default in order to get rid of the annoying (but harmless) popup about profile format. This is because we had to revert to an older version of nwjs to address one issue

Backup before deleting.
Mac and Linux users please upgrade.
Thanks for the info. I am using windows wallet, and deleted all files in ~\AppData\Local\byteball\User Data\Default dir, and now it works fine without the annoying popup.
