[Solved]Error in ogrePagingLandscapeTexture.cpp

I have downloaded the source code frow tuan.kuranes.free.fr/ogre.html
I have compiled it, but when i run my app I get an error in ogrePagingLandscapeTexture.cpp in line:
Material::TechniqueIterator tIt = material->getTechniqueIterator ();

What is the error?

What is the error?
Acces violation

I am trying to find what did I wrong
I created siplest project using plsm2, error is the same
Maybe error in my map?

Seems material is missing to me.
Did you run mapsplitter ?
Any infos in the plsm2.log ?

I have ran mapsplitter
plsm2.log? I have no such file in my directory. Maybe there is some option to enable logging?
I build my app in debug mode and another error
assert (!material.isNull() &&
String(mMaterialBaseName + " Must exists in the" + opt->groupName + "group").c_str ());
This assertion is some lines before the line I posted later.

plsm2.log? I have no such file in my directory. Maybe there is some option to enable logging?
it should be there. if running older version of plsm2 check if Ogre.log is the one updated once app is launched.
This assertion is some lines before the line I posted later.

assertion confirms the problem PLSM2 cannot find the material resource scripts needed.
Wrong directory setup or wrong resources.cfg.

My app crashes if I use these texture formats:
- InstantBase
- Splatting3
- Splatting4
- Splatting6

Previous problem solved:
I have changed this line
ResourceGroupManager::getSingleton().initialiseAllResourceGroups();
to this lines
ResourceGroupManager::getSingleton().initialiseResourceGroup(ResourceGroupManager::BOOTSTRAP_RESOURCE_GROUP_NAME);
ResourceGroupManager::getSingleton().initialiseResourceGroup("General");
So, I didn't initialise PLSM2 group, as it is in plsm2 demo.

My app crashes if I use these texture formats:
- InstantBase
- Splatting3
- Splatting4
- Splatting6
And you do have created map needed using mapsplitter ?
(instantbase, alphamaps, etc...)
