You may use the free trial version with 5 concurrent logins for 30 days. It won't save server settings (does save all users and user settings though), and it has a nag screen at launch.
Once you purchase, I do not offer refunds. Sorry! Please use the 30 days to evaluate it first! Ask questions, I respond personally to every one. If your unsure about anything, ask.

The word "concurrent" refers to how many user sessions may be logged into the server at one time. You can have as many user accounts created as you want, but only so many sessions can be logged in at once.

** - Payments with paypal can be made even if you do not have a paypal account.
