Steamworks.NET - Trying to get achievement name

Hi, I'm trying to get Steam ac$$anonymous$$evements to work in my game, but somet$$anonymous$$ng is not right. I've already created an ac$$anonymous$$evement, and I can see it from the Steam client (so it is published). And now, I'm trying to make somet$$anonymous$$ng as simple, as getting its name, but I'm just getting an empty string.

I do t$$anonymous$$s to get the ac$$anonymous$$evement name:

 ac$$anonymous$$evementName = SteamUserStats.GetAc$$anonymous$$evementName(1);

And then print the "ac$$anonymous$$evementName" after pressing a button. I'm not sure at the moment, if the argument for GetAc$$anonymous$$evementName should be 1 since the ac$$anonymous$$evement has ID "2/0" on Steamworks, but it gives me an empty string for 2 and 0 all the same.

According to t$$anonymous$$s, basic setting t$$anonymous$$ngs up should be extremely simple, but it just doesn't do anyt$$anonymous$$ng for me. Steam is being initialized, I can see my account name, apparently it does see my game too, because otherwise it wouldn't initialize. I'm running out of t$$anonymous$$ngs to debug. Maybe I'm missing somet$$anonymous$$ng really basic here? I keep wondering, the game and Steam page don't have to be finished to ac$$anonymous$$evement testing?
