I downloaded the Opera 6.20 here and until now (more than 30 days) it still functioning. Try to do this .. using Fexplore (also from here) then goto c:/system/data then delete the file name "ousr600.dat.
After deleted the file, then create a new folder in the c:/system/data name "oursr600.dat". Be carefull with spelling ...not "ousr600.dat" BUT "oursr600.dat".
However, if u still spelled with "ousr600.dat", when you running Opera, it will show that your Opera will expire after 96 days.
Until now my Opera still functioning like it was cracked.
