I keep getting this error message

[YoBlack]

not sure if this might be a problem with the actual cd-rs I have but I have been having problems installing disc 2/3 of Madden 2005 I get the error message the : A problem occurred when trying to transfer the file "...(.dat)" from the media. I have been using Alcohol 120% for that cd and tried the profile SafeDisk. Should I try another profile or another program period, I used Nero 6 and got the same problem. I have a Lite-On LTR 48125W and the CD-Rs are Memorex (700MB/80 Min).

Thanks in advance.
