Anyone got the rcbot2 plugin to load into cspromod? Options

[relentless]

I've been trying to get plugin to load into cspromod 1.04 (uses source 2007 base sdk). But can't for the life of me figure why it won't load.
This is for a listen server not dedicated.
I'm not expecting to be able to add bots and if I do I don't expect them to do anything.
I've tried using the plugin_load .\bin\hpb_bot2.dll
which just says unable to load plugin (with no other information)
I've also tried the vdf approach using an addons folder, when the game starts I can see it finds the vdf file but no other info on what happened to the plugin.
I've tested it in HLDM2 and CSS and it will load the same dll fine so I'm not sure what mystical step I'm missing(maybe they are blocking client dlls?).
I've configured the mods ini to be custom with bot CSS and directory of the game folder cspromod with a directory of source 2007 base sdk(may not be exact but you get what I mean)
I'm compiling with vs2010 (if that makes any difference.doubt it) and can successfully run the bot in hldm2. I can load the plugin into CSS but it currently crashes on addbot.

I saw a previous post of someone else who said they had got it to load in but didn't describe how they did it (or perhaps it was a preorangebox version)

Any ideas of where I'm going wrong?
