Fresh Install
I know you are unhappy with doing a new installation but it's honestly the only way to ensure your Windows 7 operates properly. Not only did you buy a pirated version of Pro, but an incomplete version since it was not an RTM version.
If you do not go ahead with a complete new installation with your newly obtained legitimate version of 7 Pro you are opening the doors to potentially many serious security issues as well as unforeseen functionality and update issues down the road.
So please take the time to do a clean install. It's truly in your best interest.

I would also file a complaint against the company who sold you the other Windows 7 Pro and get a refund asap.
