Acrobat 8 Professional Activation Type: Repair

Had a motherboard failure in a Dell Dimension, moved the hard drive to an old computer Optiplex.  Windows XP SP3 came up after many attempts to correct the BSOD's.  However, Acrobat requires activation again, is there a way to do this since it thinks I don't have internet connection and the activate by phone is no longer supported.  It's a legitimate copy and serial number.
