Tentacle Licenced on a old computer…

Hi,

I have change my hard drive system and installed a new OS on my computer and forgot to deactivate my licence for Tentacle Sync Studio on the old hard drive.
Now I can’t activate my licence on the new OS, the software said :

“Maximum number of activations has been reached. (708)”

What can I do now to use a full licence of Tentacle Sync Studio ?

Thanks for the help,
Jean mari
