Can't get Version 3.2 to work

Various versions of KNX 3.1 ran on my PC without any problems, including HDD installs.
Just got release 3.2 and all I get is a totally washed out monitor screen with distorted lines all over following the initial boot process. No changes to my hardware. Tried all kind of cheat codes, no luck there.
CD image is ok. since it runs ok. on another PC.
I have a PCI slot NVIDIA RIVA TNT2 Model 64 video card.
Any help appreciated

Boot with 'testcd' even though the disc works on other machines. Check the md5sum of the .iso you burned. Did you boot like so...

knoppix xmodule=nv (plus any other codes you usually use)?

In addition to what rickenbacherus has suggested try noddc to skip getting the monitor settings automatically.
