Problems with Font loading

Hi,

I have a strange problem with using MyGUI. I have been working with MyGUI a while ago and returned to my project now. I got it to compile again, all was well. The Demos from MyGUI (including the LayoutEditor) didn't work however and I decided to upgrade to 2.2.3 (from 2.2.2). After the upgrade my project now fails with the same Error, the examples still don't work. I'm using VC++2008.

Seems fine to me. The actual Error description is in Ogre.log:
OGRE EXCEPTION(5:ItemIdentityException): Cannot locate a resource group called 'ral~fl˜Âs' for resource 'DejaVuSans.ttf' in ResourceGroupManager::openResource at d:\ogre\ogremain\src\ogreresourcegroupmanager.cpp (line 685)
So something seems wrong with the name of the resource group of the font. Since I didn't change anything except upgrading MyGUI and the demos exhibit the same behavior (even before the upgrade) I assume this is MyGUI related. Any ideas?

Try to remove old MyGUI_Media folder and take it from 2.2.3, if you haven't done it yet.

I've done that. The same problem happens with both MyGUI_Media folders, the new one from 2.2.3 and the old one from my project.

What is real name of resource group that you use for GUI?
Also first thing that came to my mind is that you have memory overrun.

The real name of the resource group should be MyGUI_Media i think - the folder where the resources are located in the examples and i've also used the same name in my project.
Where would a memory overrun in the examples come from? I didn't change anything in the code.
