Hi @Wolfrock003gmail.com.
If you have issues with the addon, instead of leaving a bad review I would suggest you to open an issue on this adress
https://github.com/Tilapiatsu/blender-Universal_Multi_Importer/issues
with the details of the error you have, and I'll do my best to fix it as fast as I can. Thanks
Addon is not workin on 4.2 lts, error: list index out of range
