Don't worry, you were just unlucky.
The way you adjust to tight players is to shove wildly on them. Do not shove too many BBs though since it's likely you'll be an underdog when they finally call. I recommend you use hands such as T9s for shoving better than a6o, plays better against their callrange.
In most cases, you can use as a rule of thumb that the tighter the players are the more aggressive should you be. Do not turn into one of those who try to wait for a good hand to snap off one of the aggressive players with, it's just not going to work. Against people who call looser, be more careful but do not be afraid to get called if you have an ace or a good king or 55 because often they call with worse hands which will be very profitable.
Against the kind of players you describe here, you can probably shove any two from SB if they are tight enough with 10bb. If they are averagely tight, you can shove the top50% hands (all hands that beat a single random hand). Don't feel despair if you get called many times and you're totally crushed, it's just variance and bad luck and you'll often win with the worst hand which is what makes ICM work.
That is very general. To sum it up, be aggressive against tight opponents, but do not risk too much. If both have 15bb, you can just make a raise to save chips if you believe that they aren't reraising wider than they are calling with. SnG will be frustrating but if you ICM calculators tells you your move was good, then it was good and that's the end of it 
Edit: Getting called a donkey, idiot etc is often an indication that you're doing something right. Let's say the BB is auto-all in on the bubble for 150 chips, the blinds are 300/600 and the others limp to try end the bubble, I have 8K and push for dead money in the pot with 92o or whatever and they have to fold. I know "omg you stupid idiot" is coming and I'm going to like it
