NSIS Error...
 

I have downloaded LimeWire Basic v 4.8.1 and have gone to install. Upon double clicking the file I get an NSIS Error:-

------------------------------------------------------
The installer you are trying to use is corrupted or incomplete.
This could be the result of a damaged disk, a failed download or a virus.

You may want to contact the autho of this installer to obtain a new copy.

It may be possible to skip this check using the /NCRC command line switch (NOT RECOMMENDED).
------------------------------------------------------

I have since downloaded the file another 5 times and still receive the same error upon opening the file.

The following is the setup of the PC:-
---------------------------
Platform: Windows XP SP2 (WinNT 5.01.2600)
MSIE: Internet Explorer v6.00 SP2 (6.00.2900.2180)

I am also running Mozilla Firefox v 1.0.4 which is my preferred browser.

If anybody could help me sort out this installer problem it would be much appreciated. The download actually came from a download.com download.
