LWAMI crashes
 

I installed LWAMI 3.09 and after I enable the core mod and launch DW it says "Cannot Load Bitmap" or something

Some users that have reported this problem and are Vista users have found that it was caused by having DW installed somewhere other than the Program Files directory. Apparently Vista is picky about stupid **** like that.

Any solution?
Mine IS installed in Program Files (x86)

Best advice I can give is to uninstall it, reboot so the registry will recognize it has been taken off the machine, then reinstall.

I installed my copy to a directory like so:
"C:\Submarine\Sonalysts ... \Dangerous Waters"
This way it's not in the Program Files (x86) directory and Windows Vista/7 won't lock it up so you can't add the mods.

Windows Vista/7 recognize anything that is installed to the Program Files & Program Files (x86) directories as programs and so the OS locks the new directory after you install a program so it won't be modified.
I think it's just a cheesy way of exercising DRM of one way or another. I think if Microsoft writes their OS to do this, then the third party app creators will like MS even more for trying to protect their interests. But that's just my opinion, not documented fact. ;)

Unlike you say that is not a Bill Gates conspiracy.
It's for security.
If any program could edit program files folders then a virus could easily install it's self.
Just right-click your DW folder and go to the security tab and click edit.
