Not all hope is lost, for you can still potentially purchase them:
Step 1): Go to this link (
https://www.flight1.com/view.asp?page=service) and read through it, making note of the sections on Technical Support, in particular this (
https://www.flight1.com/view.asp?page=tls), Visual Studio Runtimes, and Flight1 Account Management
Step 2): Follow the guidelines of the Internet Protocol for your OS, Visual Studio Runtimes Install and create an account with flight1, with a valid email address if not already done so; feel free to run an email test on the site from flight1 to check whether or not you are receiving emails from flight1
Step 3): Visit the web archive of Sky Unlimited (
https://web.archive.org/web/20110929024902/http://www.skyunlimited.net/products.htm), choose your CFS3 products and select purchase after download option; you will download a flight1 wrapped installer of the product
Step 4) Follow the on-screen prompts, enter your personal information, payment information and email that you registered with flight1 to create your flight1 account
Step 5) Following a successful transaction, the flight1 wrapper will unwrap the product to a directory of your choice and you are free to install the product to location of your choice; note when you login to your flight1 account, you will find a certificate of ownership in your account and confirmation of a successful transaction in your email inbox. Next time you need to reinstall and you don't have the unwrapped installer with you, simply download the wrapped installer from web archive, select reinstall as opposed to purchase, enter your email address and password for your flight1 account and follow the prompts to successfully reinstall your product
Hope the above helps! Happy Flights!
