im having problems downloading the artist, anyone can help.

What happens when you try to download files? Do they sit connecting for ages & then need more sources forever? If that's the case, sounds like fake files. Check out these threads for advice & tips.
Fake files showing up in search results
How to find music (tips for video, too)

no cant see them something is blocking and its say only research results and it has a lock icon on there and it says are official limewire and then it says more info.

It could be the License warning thing.
Just have a look,
Go, Tools/Options/Searching/Basic, it says, "Show License Warning"
Untick the box if you don't want to filter out copyright Files in search results.

This option is enabled at setup, The choice is your decision.
Do a test to see if search results improve.
You can reverse this change at any time, the choice is yours.

P.S. A file that requires a license, is protected so if you obtain a license, that file cannot be shared.
So don't put those files in your shared folder.
That will cause more frustration to others as they play only silence.

Peace.

Problems with the search

If that doesn't help then delete LW's preferences folder when LW's properly closed. See point 3 below (also point 2 if you've used much older versions of LW in the past...there could be a folder in either location).
Fixes for LimeWire
This will kill all of your settings within LW's options, you'll have to go back through & reset things afterwards

The orange warning banner with the padlock was added because there's a bogus LW update showing up in search results. It's a 75.7 KB .exe & shows up as "Urgent LW update - download & install now". If people download that thing they could end up infected. To try to prevent careless people from downloading a dangerous file, the warning banner was added to LW's interface.

The padlock symbol doesn't apply to music or video


BTW, is your LW connected properly (how many green connection bars do you see)? If there's a connection problem, check here.
