Unable to compile maps

[Hamster1998]

I have just started looking into making my own maps for Garry's Mod, started with very basic map and I have found out that I can't compile the map properly.

Here is the compile log:

What I find difficult to understand is the bits where it states:

Error opening f:\steam\steamapps\hamster1998157\garrysmod\garrysmod\maps\flatgrass_huge.bsp

Sorry about the spaces between "garrysmod" and "orangebox", these do not appear in compile log I have on my computer.

Please post if you know something that could help,

Your map is too big, try making the map 128 units smaller on each side so that it's less close to the end of the grid.

Thanks AntonFTW, I have successfully built my map.
