This is what I had to do to get it running:
Upload the .bundle to the mods folder.
Do not upload the Local contents.
context-standalone.xml:
<?xml version="1.0" encoding="ISO-8859-1"?>
<context>
<script base="data" exec="level/dedicated" editor="false" language="english"/>
<mod_bundle name="bp_weapons_pack_v2.05"/>
restart the server.
We've been running it a lot on EBDA with tdm, hh, siege, and rvsa. Except for the audio bugs with the grenade launcher, etc., it's been a lot of fun!
