no audio :(
today (22 02 2012) i seem to have problems with audio on this site. there is no, so i can not complete the exercises.
does anyone else has / had (depending on when you red this) this problem?
Just to let you know, I didn't have any trouble today. You should try again because if it's not working yet it might be your computer...
also had this problem in linux and windows on the same machine. reinstalled flash didn't work. two days later on windows, it worked again. clueless about what the problem was.
