imac 10.5.8, with Flash

Can no longer watch live streams. Just a black box in the ustream viewer. It was working a couple weeks ago, then I think I ok'd automatic updater. It must have crashed after that, didn't check until now.

Youtube still works.

I uninstalled flash, then re-installed it, re-booted, etc.

Checked the macromedia global storage settings:
Adobe - Flash Player : Settings Manager - Global Storage Settings Panel

Still not working.
