access violation on init

hello all,

I'm trying to use MyGui and I keep getting access violation on gui->initialise(); from this part (MyGUI_TextureUtility.cpp):


if (nullptr == render.getTexture(_texture))
{
if (!DataManager::getInstance().isDataExist(_texture)) // <-- access violation here (Unhandled exception at 0x0031b508 in game.exe: 0xC0000005: Access violation.)
{
MYGUI_LOG(Error, "Texture '" + _texture + "' not found");
return old_size;
}
else
{
ITexture* texture = render.createTexture(_texture);
texture->loadFromFile(_texture);
}
}


here's some technical data:

Ogre version: 1.9
MyGUI: 3.3.2 (I think)

MyGUI log (nothing intresting):

any ideas?

thanks!


EDIT:
the "DataManager::getInstance()" part returns a legal pointer, the access violation comes from within the function isDataExist(), to which I don't have debug data from unknown reason (trying to figure this out).
help!

Might be inconsistent MyGUI and MyGUI.OgrePlatform. For example debug MyGUI + release MyGUI.OgrePlatform. Try to rebuild everything, missing debug data might be related to problem.

Yes! rebuilding and replacing ALL the dlls (including ogre dlls) somehow fixed this.
thanks
