My Game Won't Open

[ILikePopsicles]

I downloaded the launcher for WesterosCraft, fixed up my java stuff, and thought I was ready to start playing. But when I pressed the Play button, it went to 100% and just stopped and was stuck as "100% Done. Enjoy the server!" and won't open or load at all after that. Any way I can fix this?

Do you have enough ram? It needs minimum 4gb free to just run
