Now I see the problem.
Your Particles.pk2,Music.pk2 aren't working properly.
Look at their size.
Something is wrong with your PK2 files,I'd downloading this client then copy and paste newest pk2 made by Li to this folder.
Here's link to working client at my FTP[thanks to cybernatus for creating one]:
Download only that 1GB client,ignore that PK2 which is on FTP.
Then,after succesful download and extracting,download this file then extract it to your sro folder and replace with your current media.pk2:
Good luck!
