Having problems after installing klite mega codec pack

after installing klite mega codec pack, when i try to open my drive e, my explorer.exe hangs and becomes not responding. and results to closure of the window. this is annoying because i cant access the root directory of the drive, but when i try to access the folders inside, its seems to be ok. and when i tried uninstaling the codec pack, everything turns to normal. why is this? can any1 help?is the latest version not compatible with the OS or something? its starting to become annoying...
