Your video card appears to be a GDI Generic, wich Second Life does not support.
When I click "Yes" to "try anyway", I get
Second Life is unable to run because your video card drivers are out of date or unsupported. ...
Now, my video card drivers didn't change. SL was running just fine before I rebooted, except for one problem: the cursor would disappear in my main monitor -- a problem I hadn't seen before with the same setup, but new client downloaded since the last time I used this station monitor. BTW, the cursor disappeared in the whole primary monitor, not just in the SL application, but only when SL was running.
Now I can't run SL at all.
My system has an ATI Mobility FireGL V3200, with 128MB video RAM. None of the features are disabled, and specifically, OpenGL is enabled.
Thanks,
Jeff
