I'm not sure if this is the right section, or if anyone will be able to help me, but I just downloaded the KGS client CGoban for my macbook pro and when I try and run it, something pops up that says "your security settings have blocked an application signed with an expired or not-yet-valid certificate from running". I was actually able to use it without problems for a little bit, but I started having issue right after I updated my Java. I looked through my security settings and cannot, for the life of me, figure out what I can change to allow the app to run. It seems to me that I have the most lenient settings possible... Maybe I'm doing something stupid, but I'm not the greatest with computers. Any help is appreciated!

There's a KGS sub-forum with many threads about all these problems caused by wms's failure to maintain KGS.

e.g.

Never mind! I just figured it out. I had to change my Java security settings. Java is insisting that the KGS client is a huge threat to my computer, but I think I'm safe, right?
