HPL2 Level Editor not working

[Rapture]

Noticed your using the Mac version...

(1) Has this problem only just appeared now, or is this your first time using the Level Editor?

(1a) You have a ".map" file somewhere on your HDD, right?

(1b) Can you browse to it (Don't look at it through the "File>Open" menu in the LevelEditor) and make sure the file has a ".map" extension.

In the Mac OS X part, have you gone through everything relating to the Mac Version? Their might be bugs or what not, I haven't myself tried installing the tools on a Mac yet.
