Error in 4.02

[Tela Harbold]

After reinstalling Hoster 4.02 I have ran into a problem with some of my songs. All files were converted in 4.02, however, when I do a search and try to add a song to the playlist I sometimes get the following error message:
This file is 22050 Sample rate and only 44100 can be used.

What do I need to do to fix this? These same files worked fine in earlier versions of Hoster.
