Import SVG files as individual artboards script

[Marinapomorac]

Hello.

I want to import multiple SVG files as individual artboards 8.5×11" 300DPI in one document. I found this script:
AI Merge 
but running it in latest update of Illustrator gives me following error:

Anyone willing to fix the script so it works on latest AI?

Or am I using it wrong?
Thank you!
