Hi Caroline, sorry for the delay. I looked over your setup and found it very confusing and not very helpful, and I think you probably feel the same given that it took you so long to get through the questions even after you already had some experience with it. It doesn't account for the order of events, and order is a key component in this game.
I think the best way to think of this game is not as an Advanced Linear game but as more of a Pure Sequencing game. Some computer has to be first - that is the one computer that gets the virus from outside the network. It then passes it to either one or two others, who then pass it to one or two others, until the entire network is infected. So you should ask yourself some typical Pure Sequencing questions, like "what could go first (the one that gets it from outside the network, the first computer in the chain)". The first one cannot be R or S, because they both get it from another computer in the network. It cannot be P, because P must get it from T or U. It cannot be Q, because Q gets it from R or T. That leaves only T or U to go first, and so one of those two has to be the first computer in the chain.
Another standard question you should ask yourself in any Pure Sequencing game is "what could go last?" Here we don't exactly have a "last" necessarily, because many computers could get the virus simultaneously along various branches, but we do have two rules about S that bear watching. S gets it from another computer, and gives it to exactly one computer. That means S cannot be last, but maybe what comes after it could be? What could be the one to which S gives the virus? Not P or Q, because S is not an option for giving it to either of those. Not R, because R and S both get it from the same computer. That leaves only T or U, the same pair that are the only ones that can be first in the chain! So that means that one of T or U goes first in the sequence, and the other one goes after S. That branch could end there, or T or U could pass it along to something else. From there, the other pieces can be plugged into the sequence in a variety of ways, and you can play with them a bit if you like (a template approach, perhaps) or just head to the questions knowing that you have those components to deal with.
Focus on the sequence. There are many possibilities, but order is still an important element that governs this game.
