The AMD problem is something only AMD can fix.
You can fix it as a user too, by not buying AMD, like normal people would do
as for credits or progression etc, ED is a game like in the proper times where you truly have to find your way, it wont hold your hand, it wont dry your tears, and it is harsh and unforgiving. It is a awesome experience if you let it be. If not the game will be flat, dull and have little to no depth, content, or joy to it at all.
As for starting out, the only missions I ever did was the ones giving 100k+ credits for cargo transfering or retrival missions, not much a fan of the other missions (personal opinion). Bounty Hunting is still the best way to progression if you want a quick buck. (Y)
