I'm having the same problem but not with all files. Certain songs simply won't download properly. I can try to download the same song from different sources 10 times and will always get the file corrupted message once I reach 100%. This is usually with new songs. Could it be a file encryption that my computer can't decypher? I even tried to continue download after the warning but my Windows Media player nor my Limewire player plays the file. I can't preview the file when downloading either...
