Links with UNC path names stops working in Flash Player 14

When I'm trying to click on link to file shared in my local network area I
get an error message:

Error #2148. SWF file <http://path_to_my_swf> cannot access local resorce
\\SERVER-NAME\Folder\File.ext.
Only local-with-filesystem and trusted local SWF files may access local
resources.

This link is displaying by TextFlow and contain UNC Path like:
\\SERVER-NAME\Folder\File.ext

It always worked fine until uprgade Flash Player 12 to 14 (in Flash Player
12 it works OK).
I also tried add this SWF to "Trusted Location" in FP Plugin global
settings, but still the same.
