I had problems with the language on one of my installs, required a reinstall.
I've set it up a few times, the easiest way I found was Easydis V44 following the instructions that can be found in David's shared folder. Was really straight forward and took no time at all.
I spent months on this with a member from here where we were complicating things using a virtual diaghead and the vagcom lead. Last time I used David's instructions and it took about an hour!
