Can't load .. encode.dll message

I just uninstalled Perl 5.16 and installed 5.18. Also, I uninstalled PDK 9.2.1 and installed PDK 9.3.

After upgrading Perl and PDK, when I open the Mail::Sender (sender.pm) module I get this errors:

Can't load 'C:/Perl/site/lib/auto/Encode/Encode.dll' for module Encode: load_file:The specified module could not be found at C:/Perl/lib/XSLoader.pm line 68.

The Encode.dll is present in this path.
