Windows 7 home premium won't activate -error 0xC004E003

I installed upgraded from Windows 7 starter to Windows 7 Home Premium on my samsung n130 netbook. I typed in my key and it says it's invalid. I try to do slui 4 but it doesn't take me to the phone activation, it takes me to the screen with the options, and it doesn't say show me other ways to activate, nothing gives me an option to get it activated, just an option to retype the key, which I've done numerous times. when I type the key, it says error 0xC004E003 and it won't let me activate. I have 2 days left to activate. How do I get it activated. If I need to contact microsoft, I'd prefer to chat online as in instant message, or if not, then email. I got the key from microsoft. it is a windows 7 home premium key because I used a checker to verify it. I also need to talk to microsoft about two keys they gave me that were not home premium keys exactly, they were home premium N edition keys, which don't work with regular home premium software. Any help? Thanks in advance. I appreciate it.

hopefully this will help you:

Ring them up. You will the free numbers for your country here:

I don't have a phone to call them, and I read that link before, I tried slui 4 and the like. None of it worked

You don't have access to a phone?

You could try making another partition - use Disk Management to shrink the existing partition and create another , quick format ntfs.

Then install Home Premium on the new partition - see if it activates.

I'm sure I tried something similar to that. Still. I also tried the Product Key on another computer that I installed Home Premium on and still, same error

Did you clean install Premium?

MS wants you to use Anytime Upgrade to change in-place to a greater version of Win7. You need to clean install if you have a full or Upgrade license.
