Getting unity 2.6.1 to work again

I stopped with crashed hard drive
Filled in ticket , send to Unity the ilr file ( I paid 200$ back in time 2009 for some SERIAL NUMBER )
Unity so far did not help ( I need ilf file for manual activation )
Automatic activation writes error -50

My work stopped !
I’ll ask Unity to help again probably
May be somebody could give some CRACK or other back door support,
I don’t know
Software was paid in full
Just feeling so sad about my work stopped and my puppets waiting for me.
