Blender to Indigo not working !

So I’ve got Indigo renderer 3.0.12 + Blender 2.62.3 from Graphicall + Blendingo 2.5-3.2.5.0 installed on my win 7 x64.
I followed all instruction from main site ( File-User Preferences-install addon-Blendingo 2.5-3.2.5.0.zip-enable addon checkbox-saved user preferences-restart blender)
So I tried doing a test to see if it works. On the default cube scene I hit F12. No go !

I get this message :

[Indigo 2012-Apr-04 21:43:06] Unsupported version v3.0.12; Cannot start Indigo with this scene

Should I get new version ?

Get to C:\Users<i><USERNAME>\AppData\Roaming\Blender Foundation\Blender\2.62\scripts\addons\indigo\core

and open init.py with any text editor.

and find this lines:

            if context.indigo_engine.auto_start and os.path.exists(exe_path):
                if not version_ok:
                    indigo_log("Unsupported version v%s; Cannot start Indigo with this scene" % ('.'.join(['%s'%i for i in iv])), message_type='ERROR')
                    return

and change to:

            if context.indigo_engine.auto_start and os.path.exists(exe_path):
                if not version_ok:
                    indigo_log("Unsupported version v%s; Cannot start Indigo with this scene" % ('.'.join(['%s'%i for i in iv])), message_type='ERROR')
                #    return

(add sharp to left of return statement, line 221)

Now I get this !
