Sro_client stopped working

Hey i just downloaded the new pk2 changes and stuff, but everytime I log into my char, the client stops working immediately. Im in HT if that helps. It only happens directly with that char, if i log onto other ones, it still happens but i can atleast log on...
anyone know a fix?
I have vista 64bit

My 3 Solutions for this problems are...

1. U Re-Install the Game and Check again
2. U change the Media.pk2 back
3. U change the things u added in Media back and try again

- i Hope i could help but when i could ask,
what you added/edited at Media?
