JK Crashes after session starts

[StuartR]

I have been using JK for years.  Most recently, I have been using it at least once a week without having many issues.  Tonight, when I start up a private session or join one, it works for about a minute and then crashes.  Is anyone else having this issue tonight?  The only change that I made to computer was to install a new video card.  I don't see how that would do anything.

No problems here. There's another client update available. Did you get prompted to install it during the client startup?
