How to fix?

Info from http://www.slackiller.com/tommy14/errors.htm#numplanes:

Before you go wild, try a recompile or 2 - sometimes it is just a random thing. Also search for a brush with more than 32 faces, such as a cylinder in the Maxpoints error.
Otherwise this error means you went over the limit of the number of planes allowed. This means too many faces in the map = too many brushes, or too complex ones. Time to trim back the level map! Some solutions:
Do not put a box around your map to fight leaks. Seal each section seperately and fight the leak war.
Try to line up the faces of brushes with the same texture at the same scale. Then the engine may make them into one face plane.
Avoid detail brushes, use texture to "fake it" instead.
Plain make fewer brushes. Keep construction simple. HL and complexity mix poorly.
There are some newer compiler programs being tested that remove unused and unneeded planes from the outside of a level. You could try to get and use one of them.

it aint that but I fixed it. Changed directory for compiler.
Though I don't really get why it makes any difference where they at. :I
