Hello. Apologies for jumping in here, but I too have the exact same issue. I haven't played in months. I deleted WO a while ago, then kinda missed it. I finally decided to get back in and nothing appears to work now. I've tried the same things as Dalamarkanan above with no luck.
I've tried several other potential fixes mentioned throughout this forum but to no avail.
MBP 2011, OS X Sierra 10.12.6
Java 8 Update 144
Thanks for any advice you guys can give!
Edit: Just noticed this... Curiously, the game still launches and works (rather poorly) on my 2007 iMac, also with java 8u144. The logo has changed from the WO logo to the generic applications icon with "Stable" added to the name.
