MultiSim v10 does not work right

ok folks. i'm doing the eval for this very reason, to see if MultiSim works correctly or not before i actuall pay for it. thus far i am having lots of pain. the simulations dont match what i get off my breadboard. i'm still doing basic 555 circuits.
 
here's the setup.
 
555
Vcc 14.3v dc
R1 1.5k
R2 20k
C1 6.8uF
output of 555 has two resistors in series to GND, each is 4.7k
then i have a 270k from Vcc to the center of the two 4.7K resistors
the center of the two 4.7's is my signal
 
the sim shows the up signal at approx 830mv, but my breadboard on a scope shows ~1.2v
 
am i doing something wrong here or is the sim just not correct. perhaps some patches to the software are missing??? its very frustrating to sim a simple project, buy the parts, and then it dont work the same way the sim said it should. well, i didnt pay for the software yet, so no harm done, but you get my point.
 
can someone else sim the above in v10 and let me know your results.
 
thanks
