HEY. So check it out guys. Mine did the same thing but I have FIXED it. I'm not sure if it will work for everyone but here goes.
Go here.. Download the uninstaller for flash and run it...

(if the link doesn't work go Google 'delete flash' it's the first result)
i had to disable norton and antivirus for a sec so i could install activeX and actually let Flash 9 get downloaded..
Secondly.. Go here and download Flash 9 (42mb).. extract and install..

(again link is from Googling.. 'Update Flash'... second result.)
Lastly.. Go here.. and select agree and install to update.. but don't have any other windows open..

(this link is from Googlin 'Update Flash' as well and it's the first result.)
Once i completed the update and saw the Flash movie that said "Successfully Installed"... i went back to try and post a comment and it worked.
Again good luck and sorry for the awkward directions. Hope it works
