Well I make a new post to have help faster...
1.- My big problem is that sapien cant play sounds on my map, but guerilla can play the sound without problems.

So I tried to open the sound tags with kornman00s guerrila, but I got the following error:

Executable [C:\(Path of kornman`s guerrilla)] had the following unrecoverable error:
Couldnt find library MSVCR90.DLL required by (C:\Progam Files (X86)\Microsoft Games\Halo Custom Edition\Ogg.dll

Please ensure that is installed.

*I alredy installed the msvcr90.dll and still throwing me this error, So I reinstalled HEK with the default OGG vorbis files, I opened kornman guerilla and no problem but tool didnt can compile sounds because it throws me an exception code, So I installed Polar_bear ogg vorbis files and TADA!!!! Kornman`s guerilla cant be opened and tool can compile files without exceptions. Time later I found a new library of Ogg vorbis files (1.3.3) I installed them but it still throwing me that damn error. I think I figured out the problem of why sapien can play sounds

i've had an error in the past with kornman00's v2 guerilla and the MSVCR90.DLL too.
thing is my error mentioned adobe, so i just uninstalled adobe reader and it worked fine.
now your error doesn't mention adobe so i'm not sure but you can try anyway.

Copy and paste msvcr71 in your halo ce root directory, rename it to whatever kornman v2 wants. Done.

I've had the same problem as you before some years ago, but this worked for me. It worked for other people too when they had the same problems.

Renaming the msvcr71 worked!! Thanks :) now i hope this can make sapien play sounds

Don't rename the ORIGINAL msvcr71, make sure you always have the msvcr71, just copy and paste it, then rename the COPY.

Ok done it! :) Kornman and tools works perfectly but now... Sapien still with that damn problem! -.- He doesnt play the .scenery sounds. Well, he play the halo`s default sounds but he dont play my custom sounds. ¿WHY?!
