Office 2010 beta question

I downloaded it Friday. It gave me a code number, and requested me to uninstall Office 2007.

I did not uninstall anything. I copied all my Outlook 2007 files to the new 2010 Outlook beta, and everything seems to work perfectly.

When I go back to Outlookk 2007, it still works fine too. I thought there would be problems, but so far so good.

My question is this. After the beta download, it never required me to put in the activation code it gave me. I have tried to find a place to activate it, but to no avail. Will it keep working ok? I plan to use it from now forward, and puchase a key when one is available. Does anyone forsee any problems with my plan or questions?
Thanks,

Bill

Go to One of the program(Like Microsoft Word)
Top Left,File>Help

You should able to find the button to input your serial,
when it is done,you may use it now until Office 2010 Final release

Thanks. I did that, and it tells me the product is already activated. I guess it did it automatically. So I guess now I have from now until product release to decide if I want to spend the bucks for 2010, or just go back to 2007. So far, not too impressed with the differences. Any comments from this board will be welcome.
