Can I activate my expired trial version of Photoshop CS2 when I get my full version?

Hello,
I have been using the trial version of Photoshop CS2 for the past month and it expired today. I have a full retail CD version ordered which will be here in a couple of days and I was wondering if I have to uninstall the trial version and reload the full version with the CD when I get it or can I just activate my trial version using the serial number on the full version when it arrives?

Thanks!

It's not exactly time consuming to reinstall, so that's got to be the best advice. But for what it's worth I activated my "trial" version without difficulty (had to due to CD fault) so you can do that if you really want to.

The replacement CD I eventually received was fine, but I didn't bother to reinstall.

Hey John,
Thanks a lot for your reply. I will take your advice and just reinstall it once I get my CD.

Thanks again,
