One of our customer who bought multicardiag and install it on Win7 system computer

And when he active the software and get the license from us, there is a error appeared

Here is the error message

from the picture ,we can see that it is “Internal Error” and ask to get another “License Key”

But from the last picture, we can see that the license key had been changed to another name.

So this is the reason customer can not use it to work.

We kindly to tell that no need to change anything, just use the one we offered
