Further testing period?

Hi,
I was told that following the expiration of the 24hr test drive I would be able to have a further 96 hrs. How do I invoke this please?

Many Thanks,

David

Hi, Good morning, I was wondering if the nvidia instructions are getting through to your email? because I have been with this problem for days and I want the response of someone, because I do not know is a problem in nvidia or email.
