So this problem has seemed to fix itself. I decided to try the launcher again today and it opened. Idk what changed, but I'm happy it works.

[AzrealDragon]

Well I am glad to hear your Xmage is fixed but are you sure there is no other information that could explain why yours started working?

I have the same problem and I have tried everything I can think off and I just can not get it to work. (Launch Client = Black Screen)

This is all the information I can find after trying to launch the client..

I am having the exact same issue as the user above. The Xmage folder is empty, so something is preventing it from actually installing after the folder creation.

I am having the exact same issue as the user above. The Xmage folder is empty, so something is preventing it from actually installing after the folder creation.

After my launcher started working I was having that issue: my folders were empty and the console was blank. What I did to fix it was I downloaded the archive file without launcher from here: viewtopic.php?f=70&t=17548 (I used the second link cause the first one didn't work for me) and then extracted the file to the xmage folder. Then after opening the launcher I did an update. It said it was already up-to-date, but I forced the update anyway and that made the launcher install the java files for xmage. after that everything worked as normal.
