Here you are:
INTERNAL ERROR: Can't open file 'MAPS/Tex/Forest/summer/skwood0.tga'
INTERNAL ERROR: LoadTextureFromTga'MAPS/Tex/forest/summer/skwood0.
Tex folder is in proper place

Aha ... I am pretty certain that skwood was a standard texture for forests contained within the Slovakia map folders (an sfs file).

But if you are using 4.08 perhaps (?) it will not be included.

Here is an upload of those missing textures.

Unrar and then place in:
...MODS/mapmods/maps/_Tex/forest/summer ...

Remember this is for _Tex/FOREST/summer ....
