BFME 2 Rise of Witch King LAN problem explanation & solution

[NightMist]

I followed your steps above but when I try to mount the image file it says "the file or directory is corrupted and unreadable"
after redownloading the same file many times and rcving the same error, I even tried to convert the image into ISO. and then i can mount it but when I try to load the game, it says "Please insert the correct CD-Rom, select OK then restart the application"
does it matter the location of the image file on the hard drive (I tried to have it in the same directory, parent directory..." can u please check if the file is really corrupt or not?
Thanks in advance
