Hi Serenity, My copy is okay. It's still registered. You may not have registered it properly. All giveaways given are registered provided you follow the information in the read me file. Not all giveaways use the same registration methods so its always important to read the Read Me before you install a giveaway.
Sorry you've lots your registration.
The only thing I can suggest is that you write to Win Utilities explaining what has happened. Although giveaways come with no support, some of the better developers will listen and often will give you a new licence (if you ask nicely). Though its not guaranteed. :)
Regards

p.s. A useful tactic is to say you were considering buying a licence when the present one ran out, (or if it was a permanent licence - I can't remember whether Win Utilities is a subscription or version based program) when the product was updated, but you don't feel you've had the program long enouugh to want to definitely buy one (or words to that effect) ;)
