BricsCAD Blade DCL Preview Not Loading

Nothing wrong with the DCL coding - The DCL preview itself won't load. It gives me a 'failed to load' message once and then just does nothing on subsequent attempts.

AutoCAD's VLIDE would have a similar problem, it was related to permissions in the folder in which the temporary dialog is created. Is there, by default, a similar folder with BricsCAD that requires the same permissions be granted?

Thanks!!
