I have to say it sounds like he is lazy and does not want to commit to really learning the sim. I understand to some this maybe a daunting sim and it can be, but like anything else you learn ,if you take a section at a time to learn it then suddenly you know almost all the system and are flying and fighting with out actually thinking about it.
I really do understand how hard it can be. I have add and I have to learn complicated items by taking the small steps or I get over whelmed. It has never stopped me from learning,
On the technical side, I can understand how frustrating it can be, but I am leaning more toward user not installing it correctly. Just my opinion tho.
