Prodad Nercalli 2.0 SAL
 

I wonder if anyone else is having similar problems to me. I have paid for and downloaded the upgrade
to the above from Version 1 expert, but the installation code which I have been supplied does not work.
After several days of exchanged emails, I was ultimately given a new code, but that only produces the
same result, being rejected as "erroneous".

I have tried re-downloding and installing many times, without success. Prodad initially appeared to
think that I was doing something wrong, but having now seem to be accepting that I am not, without
yet having produced a workable solution.
