Videos and Hangeul not loading

Hi i'm fairly new to this forum so i hope it's ok to ask this question here.
I downloaded some songs (For example ALi-Hurt, Epik High - Up, GD&TOP High High etc) and for some reason neither Hangeul nor the videos are showing up. For some the video does but it's really slow and also the whole program seems like it's gonna freeze any second.
I downloaded other songs from ultra-base and those are working perfectly fine so i'm guessing it has to do with the videos from this forum. Anyone who knows how to fix this?

Oh i forgot to mention, i'm using version 1.0.2
And right now i checked again and for example when playing Tablo - Tomorrow the lyrics shown are sthg like do do do do re re re na re re O__o

Sorry for the late reply.

Some versions of ultrastar don't read asian characters. Try to install UltraStar Deluxe WorldParty 12.07 - here or here if you have problems with the site.
