Sorry Trsatfan!
I should read my email more often!
Bobs right it is a Archive not a .rar
just download it as you would normaly to the desktop and then open CM2. then all you have to do is drag and drop the file into the large window in your CM2, it's that simple.
As for the IZarc zip file, you need to extract a file with the IZarc program before you can use it, that is if you do come across a .rar file.
