Hi AntonAn,
You are welcome to update Pathfinder (and I recommend doing so), but it will not solve your immediate issue.
You need to bring your Point ID spectra into spectrum mode.
You can do this either by loading the spectrum in Point ID mode, Switching to Spectrum Mode, and clicking the Save button (or Ctrl+S).
Or, if you want to do this with many spectra, it could be easier to do this in windows file explorer.
1. open the .PS.EDS folder in Windows File Explorer.
2. Copy the .psmsa file or files that you want to use for standardization.
3. Paste them up one level into the Project folder.
4. Rename the .psmsa files to .emsa files.
Let me know if you need additional support with this.
