First move data from old Master to old Client PC (\program files\datatex\topaz).
If an old TOPAZ is running change the directory from
"C:\Program Files\Datatex\Topaz Phone Management" to
"C:\Program Files\Datatex\Topaz"
Change shortcuts to point to new Master version.
Then run reset on both PCs.
Then open the New Master version of TOPAZ first.
Then re-register TOPAZ.
If it was an old TOPAZ running also change the file path of the log file
TOPAZ > SETUP > PROPERTIES > LOG FILE
"C:\Program Files\Datatex\Topaz\topaz.log"
