Cannot render the rubber band in LPub3D, any help ??

[El-Ashi]

Good thing: I loaded your file, created BIs with LPub3D and it worked fine.
Bad thing: dunno what happens on your machine! Could it be that the folder mentionned in the error box of your screenshot can't be written?

Thanks Philippe for your help,

Yes .. you did it right. But for me I don't know what is the problem.

Here is what I've tried:

Changing the folder location --> same results (error)
Making different design in a different project file using the rubber band -->  same results (error)
Uninstall everything (Ldraw Lib , LDCad and LPub3D) and install the latest version again -->  same results (error)
Making any project without the rubber band --> working fine and can generate BI

Do you think that there is any addition procedure I should follow with a design that has  sub-model like the rubber band  yo generate the BI without such error?
