Backup PC games with Alcohol 120%

[firebirdude]

Hello. I have searched for past topics and have found a few, but none have gotten me to my goal. I'm trying to backup a heavily used copy of C&C Generals Zero Hour. Not real familiar with Alcohol 120% yet, but I click on the copy wizard, select the drive the original disc is in and then select the target drive and start. I get a ton of "read data examination errors" in the beginning, then it starts burning fine. After it is complete, the new disc autoplays fine. I click play on the menu but it never loads up. I can only assume I'm doing something wrong? Maybe something with the copy protection? I think it uses a recent version of Safedisc. If I select "Safedisc 2/3" on datatype in Alcohol 120% before I burn, I get the same result. I also got Alcoholer, but I have no idea how to use it...... or even Alcohol 120 for that matter. Help!
