nxOgre.dll crashes under Windows 64-bit :(

I just transfered all my project from my 32-bit laptop to my 64-bit desktop...now, all the programs that uses nxOgre.dll crashes...Here are some output from Windows:

AppName: nxtutorial101.exe AppVer: 0.0.0.0 ModName: nxogre.dll
ModVer: 0.0.0.0 Offset: 000170d5

anyone knows what it is wrong with the nxOgre.dll???

(p.s. we are using nxOgre cvs version - not a choise of mine, so i can't change it...and we compiled it under the release mode...)

I have a 64-bit processor, and I haven't even attempted to do so. I am puzzled why it would crash though, any chance you can narrow it down?

Also if you run any of the PhysX demos do they work?

No problems here.
AMD 64 3200 Venice, windows xp x64.
Physx driver 2.5.0 (maybe you need to update): Software mode.

thanks BlasterN, you are right!!
I forgot to install PhysX_2.5.0_SystemSoftware!!!
Now, everything works!!!

Even if the drivers is not x64 specific, It's needed to run nxOgre in software mode. Hardware mode in x64 available September/October
