Can't install LW on OSX

[rcherrero]

I had Basic LW installed in my MAC OS X Version 10.4.5 and for some reason I can't open it anymore. I deleted LW and I tried to reinstall from LW site. After downloaded the file that I get is "LimeWireSoftOSX" when I double click I get a window that it says

Alert
QuickTime cannot open the file: "LimeWireSoftOSX". It is not a file that Quick Time understands (-248)

Well I have share external hard drive with my other computers. I used my PC to download the LW file for OSX on my share drive then I opened the share drive on my MAC and copied that file to my local MAC hard drive. When I double click the file "LimeWireOSX.dmg" I get a pop up window saying:

The following disk images failed to mount. LimeWireOSX.dmg is not recognized.

Anyway. I tried both ways to download and install LW on my MAC and I can't get it to work.

Any sugestions will be very appreciated.
If you want you reply direct to my email: [email*** or I might get an email notification when you post here, I hope !!

Thank you very much for your help
