Assuming that you've done the following:
1) created a sign on account with Fantasy Grounds (which this post is proof that you did), you should have attempted to subscribe to the Forge subscription for GURPS by going to the first page of the GURPS forums here at Fantasy Grounds, and subscribed to it. Every time you logged in with your Fantasy Grounds Unity, you should have had the option to check for updates as seen in the lower left part of your screen. Click on that. It should say that it is checking for Forge Subscriptions, then state that you are downloading forge subscriptions.
2) when you start a new campaign with your copy of Fantasy Grounds Unity, you have to click on the CREATE CAMPAIGN button. The window that opens up when you do that, will require that you give your campaign a name, and immediately below the field for the new campaign name, will be a list of Game systems (rulesets). In that list - you will eventually find GURPS (4th edition) listed. Click on that after you created a new campaign named say "GURPS TEST".
3) if you selected a server type as "Cloud" - that means that anyone who looks for a game, can see YOUR newly created game with your user account name. I'm going to guess that it will show your campaign as GURPS TEST and Alpheus as GM name. Were I to do this, you would see my GURPS CHROME CITY campaign listed under HalC as GM. Problem is, I password my games so that only those who are invited may join. ;)
If you need actual real time help, let me know. Look for me on Facebook as "Hal" (and because I don't want automated web crawlers pulling my full face book name off the internet on a forum) with a last name that looks like Cramer. Switch the order of appearance for the r and a in the last name and that is the correct spelling of my facebook account.
Alternatively, you can always post here and I'll check - I'll open up a GURPS Alpheus campaign with a password the same as your name. This way, we can chat real time using Fantasy Grounds, so that I can work with you as a sort of crude tech support to get you up and running.
:)
