Hi Ragnar, thanks so much for the reply, I always appreciate your efforts to help out the community.
What is the significance of looking for non-alphanumeric characters? Can files not start with anything that isn't a letter or number? If that is the case I did I quick search this morning and found a texture that started with an underscore. However I changed this in both the textures.dat file and in the texture folder itself and I still got the fatal error message.
The only things I did in my last session was create new textures and create some custom modifiers (like a table/chair etc) but all of these are named in the conventional way without spaces.
I'll have to do a complete "deconfuckulating" diagnosis when I have more time haha.
I did read on a different forum that this error message:
System.Drawing.Bitmap..ctor(Int32 width, Int32 height, PixelFormat format)
at System.Drawing.Bitmap..ctor(Int32 width, Int32 height)

Could be caused by to much memory usage(?) Because a bitmap is too large(?) I'm not really to sure but could this be the case?
