As always, make sure your USB latency settings and COM port are set correctly. I was having this weird issue where only 1 side of my laptop's USB's were working completely. The other side worked, but gave errors.
I think i have already, not sure which version of standard tools i installed. The instructions I have first installs the basic program and then the second part installs all the vehicle specific files. I will play around.
What version of INPA and Ediabas are you running?
Could it be that i require a different setup for a facelift E46?
