something is in the incomplete folder. but i ahve no clue what it is. there is 2 things in there. but when i double click on it, it doesn't play it or whatever.

what limewire manual?

You obviously didn't see the Sticky at the top of this section. Manual http://www.limewire.com/english/content/userguide.shtml

There are the downloads.dat & downloads.bak files in the incomplete folder. These should never be touched!!!

Check to see if this is your problem & check the options discussed: License requirement (click on link)

If the files aren't even going into your download window, then they must be either fake or else, you need to change the setting for downlding license of files.

The two files in the Incomplete folder are the bak and dat file of Limewire; don't touch them !! LW needs those files to write down which opart of which file it has already downloaded.
If there are no other files (except those both) then LW hasn't started to download anything.
The best thing for youy would be to start reading the manual, as suggested by LOTR. Go here:

Depending on your download speed, a music file with some 4-5 MB will need up to 10-15 minutes to complete the download.
