Hello,

I have a Dell win7 installed in my 1525 Inspiron that my updated PC would not accept for performing a system repair. I downloaded an up to date version of win7 from a third party (with no activation code) then I was able to repair my system, but now my new win7 OS does not accept the activation code of my original win7 disk, what can I do, my situation is desperate as I do not know if my system will lock out as it is always stating "your trial period is over".

When I enter my valid activation code from my old win7 disk I get a "invalid activation code" message.

What are the alternatives!
