ARToolKitPlus & Windows8

Hello everybody…!

It’s possible that some freeframe nodes dosn’t work the right way with Windows 8? I’m struggeling with the artoolkit node!
I even rent a ps3 eye to be sure about this “.dat” File thing. It doesn’t work right, I get the right Marker ID but the Matrix Data is strange. So I tried with an old win7 notebook and it worked. So…hmm

Somebody any explanations?
thx in advance for any hints!
