Maybe the code was fixed, not sure, but I'm still having a problem 2 years later with v7.3.1.
My issue is a missing file, _fp_Greenwall1.max, I ran a search for such a file on all hard drives and it can't be found.
I tried uninstalling and reinstalling the Vertical pack and still have the issue!
Image attached with error.
Any help would be greatly appreciated!
