We guarantee the safety of our software if downloaded from this site! We are in the process of obtaining a code signing certificate that will provide peace of mind and eliminate problems with software installation. At the moment, please understand that we are a small user-supported community without such a certificate. That means that your system will likely warn you about downloading software from this site. This has nothing to do with the software itself. Rather, It's due to the lack of a code signing certificate in the software executable. We apologize, but this is our way of keeping costs to a minimum. We hope you are undeterred by this and choose to work around it (see below for workaround).
Important: Our software is only for Windows operating systems and requires a desktop/notebook/laptop PC.
Get Started by Following these Steps

| Custom League License for Solo Play Only (Unlimited play for 1 month). | Play in 1 Single-Season League for duration of league. | Play in any 3 leagues of your choice for 2 months duration and design your own leagues to sim (includes 2020 - 2023 season pack). |
2. Once your payment is received, we will open an account for you and post a URL link to your customized software installer. Whatever address you use with PayPal will receive this link! Please allow a little time for the email to arrive since it requires manual processing on our end. Note that the portion of your email address before the @ will become your username by default, so if you want something else, please let us know right after payment by emailing
3. From the email, click the download link to download and run the installer. The installer inscribes your personal NSB account info on your local PC. See the workaround below if your Windows OS tries to block the installation.
4. After installation, we recommend that you add an "exclusion" or "exception" to your Antivirus Software for the two main software directories so that it will not mistakenly identify our sim as a threat during a scan. The directories or paths needed for the exclusion can be seen at the bottom of the Launcher Window (see below) when our software runs. If you don't know how to add an exception or exclusion, do a Google search, e.g., "Adding Exception or Exclusion to McAfee Antivirus."
Use the Join your First League or use the League Designer buttons to join or design your first league!
