I can start LimeWire and connect, search for stuff, but when I go to download something the item says connecting but wont budge...it wont download at all just says connecting...

now after a long wait it says need more sources which isn't right cause it says 100...also this doesn't happen with one spacific item but all downloads...

Those things that sit connecting, then show need more sources are probably fake files...they're all around now & are a PITA.
Search again, vary your search terms, try the All Types search. Stay away from files with lots of sources, go for a file with 10 sources or less, or those with a modem source.

For movies, always check a file before download with Bitzi. A file with heaps of sources but no Bitzi rating is often a fake.
