Cannot load SVG to laserweb


I tried laserweb for the first time.

I tried to upload different svg to LaserWeb , but with each image i see only a message: “Unsupported file type:document/ConceptDrawDIAGRAM”

I created the first svg with inkscape. A later i tried to upload a png, then use laserweb to trace/filter, save as svg. Then after reload the svg created with laserweb the same message appears.

Which point am i missing?

I use the actual Windows 10 version, also tried actual chrome with new download. Downloaded the actual Win64 exe of laserweb - all possibilities had the same output. What am i missing?
