Yeah yeah, newbie's error, but I yet forgot how to fix it.Upon exporting, I get the "MakeMDL was not found bla bla" and the "Export model failure".Any hints?Thanks. :-)Etienne

Make sure the decimal symbol is ".", not ",". You can edit Your settings from Start > Control Panel > Regional Settings. Hit the "Number" tab and change the decimal symbol. Hope it works.

Ah, damn...Yup, that was it.Thanks dude, thanks a lot. :-)Etienne
