I have tried everything listed in this thread. Nothing helps. This problem seems to have gotten much worse as LimeWire was upgraded. I am using 2.8.5 Pro and it just gets worse and worse. The majority of what I download "cannot be moved to library". Some of the files which are MPG (etc) I can preveiw during the download though. I find it hard to believe it is a problem with a file name. Help someone Please.
