Hi there,
I am running on a MacBook Pro 2.9 GHz Intel Core i7. I recently updated my computer software system to Mavericks OS X. Then, I tried running Spiral Knights through steam, and it closes immediately as it begins to load. I installed JDK 7 Update 45 before I tried running Spiral Knights on Mavericks OS X, so maybe that's the problem? Is there a way to remove JDK 7? Thanks for your help.
I also sent an email to support about this issue.
