im trying to make a map right now at im at the point where i use sapien, it worked b 4 and i clicked game window to look at map, and it look ok...,soooo, i couldnt find a way to get to hatchery window (er whatever its caled :P) so i exit the page startup again, and it worked but i didnt double click the right button (accidentally) so i exit it again and startup i worked(again)... adni brougt all the pages up in sapien and it closed out automaticly i startup and i get this white page it wont go away, no matter how many times i start it, i uninstall reinstall, still no dice, make map over ,still no work, so i ask "What do I do?"

The "white page" means that Sapien is loading. You must wait for it to complete. Either one of two things will happen.

1) It opens up. Joy.

2) It closes itself. That means that something's corrupted, or you're missing a tag. Find a file called debug.txt inside your Halo Custom Edition folder, copy the last few paragraphs, and paste them here.

move the white window out of the way to reveal the other windows.

ZOMG IM STUPID thx for the help it works fine now ^^
