Did someone say 42!?!?!?!?! No wonder it won't display. The servers were so shocked ans surprised that you obtained 42% that the programmers realized that it would crash the system. They changed it to 41% for the safety of the universe. If you obtain 42% resistance, than the Vorgons will invade! They will sense the disturbance created by obtaining the answer to Life, the Universe, and Everything! Then they will read poetry!
Think of it this way. If you convert that percentage to binary than you get a full 101010%, or in Octal that's 52%, and in Hexidecimal that's 2A.
