I have Limewire 4.8.1 Pro. A friend gave me this copy. When signing into LW I received this error message: Limwire was unable to open a necessary file because another program has locked the file. Limewire may act unexpectedly until this file is released.
Why?

How do I find the program that locked it? How do I find which file is locked? Now all saved files are pink. I am using skin pink/black. They will not share. I can add other folders from my computer to share but the ones I have downloaded to LW will not share.
Please help me!!
