Hi! 
Newbie over here... -also a non programmer, non native english speaker. Just a biologist interested in music and cognitive sciences.

I'm trying to make a set of drumpads using Pd so I installed Firmata 2.2 as well as Pduino 0.5 from the Hans site: https://at.or.at/hans/pd/objects.html

I tried to run it but I get a bunch of "couldn't create" messages like these:

Loading plugin: C:/Program Files (x86)/Pd/tcl/pd_deken.tcl
[deken] Platform detected: Windows-i686-32bit
Loading plugin: C:/Program Files (x86)/Pd/tcl/pd_docsdir.tcl
The Pd window filtered 9 lines

[arduino]: version_0.5
Pd documents directory: C:/Users/Elisa/Documents/Pd
PatchToCommands.pd 15 0 16 0 (text->text) connection failed

I've tried to change the externals path so that it matched the Pduino Folder but still getting the errors

I'll really appreciate any help, it'd be important for letting me use Pd for my undergrad project. 
Bests,
Eli
