I made the update of the wallet to the new 2.0 version.
All is working fine but I have a message o the launch of the wallet about my profile is coming from a newer version of NW.js and I have to change my profile directory (?) or using a more recent version of NW.js.
I had this kinf of message with my previous version of the wallet.
I use Ubuntu 14.04 (up to date).
