Perhaps Adobe's trial period day counter is on Adobe's end. Even though you only used it for 10 days, if it is a 30 day trial and it took you 3 weeks to get your laptop restored, you'd be on the 31st day and thus beyond your trial membership.
And since your next question with a "

" asks how to change your IP address, I am guessing it is on Adobe's end and they track your trial period by IP address.
Why don't you try
The Gimp or
Paint.NET? They are both free.
