I sold my old pc and re-installed Audio Visual Math's on the new i5 PC with Windows 10
All goes well until register, I register first time successful and then as it re-opens after successful register it comes up with two messages that says not registered. No matter how many times I insert the code and get success the same message keeps coming up.
I have re-installed a few times, also clean out as described above to no avail? Any suggestions?
