Ermm..isn't it against forum rules to discuss such software? :-/
A trial is a trial and you are supposed to use it only for the said period. Not after that.
It is against forum rules to discuss ways to use software beyond their trial period. As eddie said, a trial is a trial and using it beyond the stipulated period amounts to piracy.
@anandk: You've been here long enough to know that this is against forum rules.
