Thankfully to the database's file uploading system, a new mirror for downloading Renegade Resurgence was set up. The two files necessary to play the mod are now available from the Renegade Resurgence --> Downloads tab.
I hope that you will no longer encounter any broken links while trying to get this mod. It's a common complaint about RR, and generally about mods which were released a long ago.
For those of you who encounter any problems, you are encouraged to contact the creator at firstname.lastname@example.org.
