Blank welcome sceen can't open project

I’m running defold on linux 32 bit. I’m a total noob on working in linux, just running it cause it’s lighter. When I open Defold I get a blank welcome screen and can’t open project.
I’ve tried redownloading the engine and run the .sh script, it didn’t work. when I try to run the script I get:

Gtk-Message: Failed to load module “pantheon-filechooser-module”

(Defold:27520): Gtk-WARNING **: Unable to locate theme engine in module_path: “pixmap”,

Gtk-Message: Failed to load module "canberra-gtk-module"
ERROR: Resource type for extension ‘gui’ already registred (com.dynamo.cr.guied.resourcetypes.gui)

Please help!

There are some requirements listed under the FAQ, in particular the installation of the webkitgtk. What version and OS do you run?

I’m running elementary OS 0.3.2 Freya 32 bit
