XAT

I know this is not the best place for my problem but I couldn't find
any other forum on xat.professional image optimizer.
After rebuilding my computer I had to have release code again.
It was send to me but I have the same message constantly that the
code is not correct.
I need help to find the place to resolve this problem, the email
address info xat.com is working but I have no replay from anyone .
Can anyone help me out where to find maybe technical support, or
someone to communicate with.
Thanks Eva
