Hello,
I had to install the newest java version for another game.
When you run the installer, it asks you to automatically deinstall older java versions. Now, I didn't uncheck that option, so the required version to play offline 1.8 (Java 8 Update 60) is now gone. It doesn't run with the newest java either...
What can I do? afaik, java 8u60 is not available to download anymore, so I can't just re-install it again :/
