Corrupted files
 

I have been using Limewire for months without any problems. Now, suddenly, 90% of the songs I download are corrupted - or at least that's what the software says. This happens too often for me to put it down to bad luck. Does anyone know what is going on? (I recently ugraded to Mac OS X.2.3)

Do I need to reset the preferences somewhere?
Is it advisable to throw out all corrupted files?

Many thanks for your help.
