Mismatched RSL's usually means Adobe caching problems. But the causes of it could literally be endless. Starting with removing programs the wrong way, or incompletely, which makes a mess of dynamically linked libraries in your computer.
I'm not even going to try to explain how all that works, but your basically verifying what I've been saying....there's something wrong on your end and I'm sure there's others that have the same mess going on.
There's millions of people using the updated chat, so we know it works fine.
If you have updated your Adobe flash player, about the only thing I can suggest at this point, would be to completely remove Adobe Flash player and then reinstall it.
If you uninstall programs from your computer by deleting them, then all bets are off, and it's too late anyway.
