Looks like it is missing a texture from the error.
If you go into the editor it over writes your init file. So you have to change that everytime you try out the map in BF2 (if you do not make the file Read_only)
And make sure you add
run ../../objects/common/spawners/spawners_common.con
run ../../objects/common/spawners/spawners_usa.con
run ../../objects/common/spawners/spawners_mec.con
Does any of your spawn kits have ziplines? That is what the error looks like what is missing the texture.
I am no expert. Hope it points you in the right direction.
No sorry ... doesnt help much... init.con is allready read-only and these lines are added, too. (got them from Khashan; the "Project Reality Mapping Guidlines" are a little out of date (0.75 )
