So back and re-read the beginner's topics and follow the instructions to the letter on how to load the daten.
EDIT: I'm feeling nice today, and I'll only do this once. Attached is a link to the *complete* NCS coding data from 45.2 (it has the sgdat, daten and ediabas\ecu directories from every chassis). I know these datens are loaded properly and work because 1. I did it myself and 2. They've been tested. Extract and copy the folders to their correct locations. If you are still having problems, then something is wrong with your installation. If copying these files into place makes everything work, then you loaded the datens wrong in the first place and need to re-read the getting started threads.
Hey, I've been having the same problem. I already had v45 and I also downloaded from your link but I still do not have any .grp files in either ecu folder. Do you know where I can find these files?
