I reinstalled JO, and there's a cyclic redundancy error when it gets to assets0.pk3! plz help!
  
 
  
  
    clean your CD, and if its scratched badly, you may have to get a new one.
  
 
  
  
    Fanbill is right on the money.
 
 I had this exact problem two weeks ago when reinstalling JK2.
 
 All I had to do was rub the cd on my sweatshirt a little bit.
 
 It's totally a CD scratch/read problem.
  
 
  
  
    Back-up the cds or buy 10 extras for emergency :D
  
 
  
  
    Use a virtual drive. Its very handy.
