Need help!! Why is it telling me, it can not move my downloads to my library?? What am I doing wrong and how can I fix it??

Can you be more specific about the error message? By LIBRARY do you mean the LIBRARY section of LW or your own LIBRARY where you keep your files? If it is a holding folder that you are moving files too and LW is using it, you can get a message saying file in use. You will get this or a very similar message if you try to change the name of the file if it is in use by LW or another application.

you get that error message because LW does not know where to move the files you download to.
too fix it go to tools, options, savings, and than click browse and select a folder where you want LW to save the files. the default is Shared folder the path to it is usually c:/program files/limewire/**shared folder** this is for windows users.
also make sure that the folder which you select to save files to does exist and is working right
