When I try to open prepared
.amf plate with some items to print, Prusa's Slic3er release throw's this error:
The slicer version is 1.30 distributed for Prusa's i3 MK2 1.75 printer.

The slic3r software is written in Perl, a programming language that can be expanded with local libraries. XML::SAX is one such library. CPAN is a tool which can be used to retrieve libraries from the CPAN repository (Comprehensive Perl Archive Network, I believe).
I use CPAN is something I do infrequently, so I would be doing a disservice by trying to list the steps here. Better answers are, no doubt, on stackexchange. Nevertheless, these may help:
From your command line, start Perl running the CPAN module, and invoke the CPAN shell (your input in bold):
> perl -MCPAN -e shell
cpan> install XML::SAX
cpan> ... several lines of output ...
XML::SAX is up to date (0.99).
With that done, try using slic3r again.
