Photoshop Elements 10 Reactivation after a crash

[Tim3860240580ax]

I have a disk copy of Photoshop Elements 10 that has always been all I need without upgrading. I recently had a system crash and lost everything on my hard drive. When my new computer arrived I got out my disk and installed Elements 10. However now I get the pop-up shown in the attached photo. I can't "deactivate" my old copy because that computer died. Is there a work around to get my copy of Elements onto my new computer??
