Thank you for this tip. It works.....

Hi Fredo,
I try your instruction. But it doesnt work.

Hi Fredo, I upgrade to 4.0.0. The aktiveprocedure was a little different. OK, over again, I bought a full License. I got a new scflicense. But it doesn´t work again. My computer was always connencted to internet and I´m a skechtuo pro.
I pay yesterday 8,61 EUR and today 16,24 EUR without succses. Im a little bit frustrated. Usually i love your extensions

I bought the license but an installation still doesn't work.
