hi again..
As I remember i have also had some problems with flash player....
Just for fun try to disable SeLinux (in /etc/selinux/config -> SELINUX=disabled) to check if it is the selinux issue...
Assuming to your post you have installed from the firefox browser...I have also had problems with this...
Just try to delete all plugins and install player from URL from previous post of mine...
For me, firefox 1.0.4 works just fine, but you could try this one:
