My first load is about 2 minutes, slightly more than 1 after that.
That still doesn't account for barely 2 minutes of trial time.
Yes, it does, 2 minutes for loading + 2 minutes of trial = 4 minutes. The Trial lasts 5 minutes, but if you start a Flight to a Trial-enabled airport, the counter starts as soon as you select the airport NOT when you press the "Start Flight" button so, even the time you take to select the weather, the airplane, the time/date will count.
That's why I suggested to start to a nearby airport which is outside to the Trial area so, no counter will start, and if you move from this nearby airport to the trial one after you are already there and your airplane, weather, date/time are already being chosen, the load should be very fast.
I also dislike the hoops I have to jump through to get everything installed and running with my virusscanner.
That's because your antivirus is flawed and is mistakenly thinking our modules are thread, wrongly labeling as false positive. Not all antivirus do that, the free Microsoft Security Essentials, which we use, doesn't do that for example, and is not the only one. Only some of them require to do this, and improving reliability against false positive should be something the antivirus developer should do.
Unfortunately, they seems to do exactly the opposite and, for marketing reasons (being able to brag about their ability to discover more virus than the competition), they end up making the system unusable, because they flag as threats lots of legit programs too because, instead of relying on a database of files that are *proven* to be dangerous, they rely on heuristic methods, which are very unreliable.
I have my MS Security Essentials A/V configured to exclude my whole FSX folder, and never seen a false positive message, nor I had to ever turn it off, nor I had to ever change its configuration after doing that initially.
