In-game BPs cause instant game freeze. Assistance? (PAL)

[TrueStorySeamus]

Hello.
I am having problems getting in-game battle portraits to work. CSPs work fine, as well as SSPs, but in-game battle portraits just don't want to work.
I am putting the files into the info/portrite folder as instructed in multiple tutorials, but to no avail. I was able to find a download that offered all the .brres, but after editing them, it just ends with the game freezing.
I'm using a PAL copy of the game and use Riivolution to load mods.
Any help to this query would be appreciated. Thanks in advance!
