Reclaimer - No functions work?

Hi there,
So I've recently installed the latest version of Reclaimer, but none of the functions work? I can open .MAP files in the browser, but "Open With..." and "Open" don't do anything. Also tried batch extracting the .MAP as a workaround, but despite saying it completed the extraction the folder was totally empty.

Also I tried to add Architect, but there was no plugin folder when I installed either. I downloaded the "Reclaimer-1.6.285" zip (and I unblocked the zip too) from the GitHub and extracted it's contents to the Reclaimer folder, then put Architect into the plugin folder, and still nothing worked.

Any help please?
