When i open my download file it crashes in a few sec. & windows says must close
 

Why when i open my download file it crashes in 5 or 10 sec. and windows tells me it needs to close.

I'm not sure what you're talking about.....

Do you mean that you go to your shared folder using Windows Explorer and when trying to open it, your computer crashes?
Or do you mean that you try to go via the LW Library to the shared folder?

If it is the first one, and it would be my computer, I would check first whether I caught a virus with the last file(s) downloaded; though I don't want to scare you........just a thought of mine.....

no the folder crashes

format computer and is still doing it

Try to search for one file in that folder via START>Search>Files and Folders.
When it gets displayed in the search results right click it and choose "open containing folder"

If this also causes a crash, go over that folder with any Antivirus/Spyware/Maleware program you can get a hand on.

No virus tryed all that, i formated my HD. and installed limewire again AND IT STILL is doing it. MY other folders are find, just limewire download folder is giving me the problem.

I got it off the offical website and it is basic

Step by step, tell us exactly how you make that folder "crash". We need to
know exactly which part of the operating system or which software you are
using when that happens.

In windows explorer i go to limewire download folder and open it and 5 to 10 sec. later windows tells me it needs to close it and i must click ok and it close it . i have try formating my HD. because i thought i had a virus,and installed windows XP sp2,and limewire again and it is still doing it.
