this morning system says I don't have a valid license. Not true. Please fix so I can access my email.

I have a valid license. System says I don’t and when I re-enter the code, it is not accepted.

Dear Harry,

The issue was caused by an error in our Licensing system and we worked hard on a quick fix. 
By now you should be able to continue using eM Client. 

We apologize for the inconvenience.
