Solved Can't reinstall Windows 8 upgrade

Hello,
I was running Windows 7 Home Premium (a OEM installation that came with my DELL laptop) when I decided to upgrade to windows 8 through the Assistant; I have made my media (DVD), but ultimately installed from the link on the desktop. All went well. After the installation I couldn't reinstall my Office, so after fooling around a bit, I decided to make a clean install (BIG MISTAKE!). First time I couldn't validate my key (as it was for upgrade only), but I got it installed and running without validation. But to validate again, I was told, what I really needed to do was reinstall my previuos version of windows and reupgrade using my key. Well... I didn't have a media of my previous version of the OEM windows (I know... I'm stupid, should have made one first). Anyway, I got a media of Windows Home Premium 64bit (english version this time) and validated it with my original key. After a day spent finding suitable drivers and downloading updates, I got my system running again, ready to reupgrade right? I wish! If I run the media of Windows 8 through windows it won't validate the Key I bought in the beginnig; if I try to download again the assistant, it makes me go through the buying process again, and futhermore, even starting the system through the dvd won't do it anymore, it just refuses my key and won't go through!!! Can anyone help me? I'm running out of time, need my laptop to work ASAP. Thank you.

Look for the link in your email from Windows store.

Hi again,
Thank you Theog. It looks like the time I spent searching for drivers for Windows 7, on top of tired, made me dislexic as well: I switched two digits of my key... So sory to bother! Again, thanks.

You are welcome, well done.
