Hello,

I bought a regular Mulab license key, paid by paypal.
I installed Mulab on my PC and entered the key.
Everything worked well until today when mulab asks me to reenter the license key. When I enter it mulab says "invalid license key".
Please help me.

Have you installed a newer version? did you copy all the numbers correctly?

You als emailed me about this right? In that case you already got reply and all should be fine right?

You most probably are still using your temporary initial user key instead of your permanent personal user key which has been emailed to you.
