Version 0.3.1 of iSlsk fixes a bug a few people were experiencing with version 0.3 of the application. It seems that some people were having a problem with the music freezing while it was importing and therefore never completing the download. I did not have this issue with the previous version so, I cannot tell you for sure that it is fixed. Let me know in the comments if you were experiencing freezing and if the update fixed it for you. You can get iSlsk via the BigBoss source.
