NUMBER NOT WORKING

[ADDABAD]

I bought a paid for Nisus Writer Pro. All was fine until today. Now it want me to enter my license again. Fine. Now, when I do it says "invalid". I am asked to buy again.

I'm going to assume this is the same problem you posted about already (you bought a license for Nisus Writer Pro 1.x, but are trying to use version 2.0). If I am correct, you will either have to buy an upgrade for version 2 or go back to using version 1.4.1.
