Do I have FGU or FGC?

I bought an Ultimate license of Fantasy Grounds earlier this year on Steam (v.3.3.12 Ultimate) but I can't tell if I have the Classic or Unity version?

How would I figure this out?

If the version is 3.x.x then you have Classic; if it is 4.x.x then it's Unity.

And welcome to FG.

Awesome, and thank you.

So, is the Free Demo Unity? If it is, will my players be able to connect to my version?

Classic and Unity are completely different programs and can't be used together. So if you have Classic then your players will need to use the Classic demo. Both Classic and Unity have demo, standard and ultimate license types.

Ok, thanks!
