Sorry for being impolite. Was a long day :-(
The error messages from the FAT95 driver are in german because you copied the L:Fat95 file over to your harddisk
instead of using the supplied installer scripts.
If even V2.x doesn't work, there's something majorly wrong. The licence keyfile is stored inside the device driver (both V2.x for old subway batches and a V3.x keyfile for the "new" batch also sold by AmiKit), that's why it cannot be found on the installer disk. The license should be shown in the Hardware Info window when you double click on the subwayusb.device line in Trident.
Why this doesn't work is a mystery to me. The Subway with the V3.x license is out now for more than a year and we had no reports for malfunctioning except one similar case in december.
If I would be paranoid I'd suspect sabotage of some sort.
