Well, since they licensed Razer to make a gaming keyboard for SWTOR I'm rather inclined to doubt that they will offer support for a Logitech product. Sorry.

I am the poster boy for League 4. I've been playing solo for six months and having a great time.

OK, I am a noob myself, or at least generally oblivious, so if I sound like an idiot (It's true actually) please forgive me. If you open the local map there should be a green single arrow, as opposed to the double arrow for the taxi. If you hover over that arrow it should bring up all of the mission objectives that are in that direction and if you click on the arrow it will open up the map that it is pointing to. If you keep going from map to map you should be able to find the objective point. I had this problem too and found that the turn in point was in a building that I hadn't been in yet but when I clicked on the arrow it opened a floor plan of the building showing the drop box I was looking for. Hope this is helpful. (Or at least assures you that there is someone far more clueless than yourself out there.)

Are you wrong to think it was a bad ending? Not if you didn't like it. I wasn't thrilled by the way that it worked out but I wasn't as disappointed as you seem to be. Is there a choice that changes the way that the story plays out? Not that I have found. I have played it through a couple of times and that is the way it went both times. What lore reason for it to work out this way are really immaterial, I have to agree with you that it does seem a bit anticlimactic. But I will say that the Inquisitor is a lot of fun to play, and I really like Lord Zash because the more I interact with her the crazier she seems to get.
