how do I open file center?
 

I got limewire about 2 months ago. I had an icon on my desktop. I downloaded a few songs. Next day I tried to get online and lime wire opened instead of my homepage. Felt I got hijacked. I can not remember if I deleted the shortcut on my desktop but I managed to get back to my homepage opening instead of limewire. Now I wanted to do some more downloading and I can't get to a limewire sign in so I have access to the files. I did a search and I have several limewire files but none that open it. I got to the site with it's url but no place to sign in there. Can anyone tell me what I should do from here.
Thanks
