There are 2 ways to get the program non time-locked. The time lock limits you to about 30 minutes, enough time to work out if it runs or not, and if you can get it communicating (which is easy, if you are getting stuck, just look at my support page, and then email me).
The first is a registration key file (I can personalize one for you) - which you can download off the downloads page.
Alternately type in the registration
  1. From the main screen, either right-click on the title area and Select "About", or click the "About" toolbar button.
  2. Click the "Register" button
  3. Enter the registration name : Completely Free
  4. Enter the registration key : 66840713
  5. Click OK (button is disabled until you get the code correct)
This simulator is free, if you do like it and want to encourage it's development, please donate using the button in the sidebar to the left:
Really Free? I'm not asking a license because there are some guys out there asking as little as $20 and then never actually improving their offering. By keeping it free, I put pressure on the bigger guys to offer a better product to you. It costs me about £15 and around 50 hours a year coding and replying to emails to host the website, your donations and bug-reports mean more people benefit.

Basically I have an unlock code system in place because it helps me get an idea of how many people download my program from various places - if you do want a personal unlock code, please feel free to make a donation. The unlock code can be used on as many computers as you want.
