Yes, that's correct. There is an exclamation point next to each song. (sigh) I had a feeling I would have to re-download all the songs. My computer was also running slow and I have DSL so I did a thorough cleaning & defrag. so I guess its gone.
I deleted them from my LimeWire library because I thought it might make my pc run faster.
waaaaaaaaaa!!!!!!!!!!!!!!!!!
