Maps not loading

Hello,
I have a very frustrating problem. When I have a downloaded model in Vray that I need to convert in Corona, when it converts the material the maps are somehow not loaded. They show up in each spot with its name, but I have to load them from the folder again so they show up in viewport and render. I add the maps beforehand in Customize User Paths.

Any suggestions are welcomed
Thanks!

I use the above script.

First relink the bitmaps to your new location. Then corona convert en after that select all and show in viewport.
