Star Trek Online

Guys, I have no clue what I'm doing. I don't even do if I have the right game. The first question of idealism is that the game we are supposed to download is, in fact, Star Trek Online - Mirror of Discovery, right? I feel like I'm going mad; stared Cthulhu in the face... Anyway, the second question of idealism is that one quest gives 1 lv, right? Am probably missing something, but it took me a whole day to get to lv 4 because the damn quests are like 15-30 minutes long. The GUI is so freaking complicated (not actually) and I'm using a windows 7 so I can't even run the game well on the lowest settings... I might be a damn fool, but I'm venturing out... out to see if anyone's there or I. might. have. gone. MAD.
