I downloaded the wad after a search on the forum, but it doesn't seem to recognise that the textures are the same i.e. it can't find the required textures in the wad.
Can you just send me the wad in email (christianjdavies[at]googlemail.com or something?

Ah sorry cant send it, I just realised I overwrited the was I used with new texture for the new castle.

The textures were only temporary anyway
