Mapping is not dead yet

[ZonElax]

If there is any mapper around, please I'm begging you to help me. :S I'm just about to quit this sht. I don't know what's the issue but computer doesn't let me build nor save nor test my maps. Always some error, for example: multiple script_multiplayer, tree value backwards, max planes surface,... can't find .bsp file (I have compiled it 1000 times).

I'm really upset about this and I can't find any help on the internet.

Thank you
