A simple solution which may work for you is as follows:
1]. Download IsoBuster V1.4 [www.isobuster.com]install and reboot.
2] Place the corrupt CD in the drive used to burn CD's and hold down the right "shift" key.
3]. Start IsoBuster and select the CD drive where the CD is located.

IsoBuster will read the corrupt CD and show all data. Simply extract the files to your hard drive and reburn.

NOTE: This only works with IsoBuster v1.4. More info on the IsoBuster web site.

Hope this helps you out.
