GS231178

Hello folks, So I've been following the F&L guide and started a playthrough. All seemed well until I made my way up to the REPCONN building. http://imgur.com/428S8hg That was the first glitch I noticed, then upon entering REPCONN, I witnessed the following: http://imgur.com/vzDz6Mp http://imgur.com/GbhSOb6 http://imgur.com/6Obpo8r http://imgur.com/QicWy75 And then on my way to Boulder City: http://imgur.com/HYkmr1d http://imgur.com/l3VQ5xm To the best of my knowledge, I followed the guide to the letter. I'm using NMC's Texture Pack (Medium) and Poco Beuno. I did have an issue when I attempted to optimise the textures using DDSOpt, again I thought I'd followed the guide to the letter but I obviously made a mistake (not sure where) when uploading the optimised textures to Mod Organiser, as all I got was missing and weird textures, along with the white exclamation mark/red square. So I removed the optimised textures and haven't tried again. Can anybody shed any light on this? I've made a mistake somewhere, but not sure where.
