Why does my computer keep saying Shockwave Flash crashed?

So, i tried going to a TinyChat server with my friend, and it said Shockwave Flash had crashed. So I uninstalled some things on my computer, then I re-installed Shockwave. Then I try going to tinychat again. Guess what? Again it says Shockwave Flash crashed. Why does it keep saying this and how can I fix it? I use google chrome, if that helps at all.
