fluidsynth~ error 14001

Hello,

I’ve downloaded fluidsynth~ from this link :

http://recherche.ircam.fr/equipes/temps-reel/distrib/fluid4max.zip

I placed the mxe and help files in my "external" max folder.

But when I try to create the object in a patch I get this error:

Error : error 14001 loading external fluidsynth~

It sends the same error when I load the ".help" patch.

Does anyone knows what causes the error 14001 ?

And how can I make the fluidsynth object work properly ?

Thanks in advance
