If I want to buy Spectralayers 10, I get a "page not found 404" error

As the headline says.

I’ve used my whole trail months now, and the “activation manager” is popping up on each start of Spectralayer (one day left). I can choose to dismiss or buy the program. When I choose to buy the program, I’m getting the mentioned error?!

I guess the link is hardcoded into the activation manager, and the destination address has changed.

Thanks for reporting the issue. Can you see what wrong destination address is opened ?

Anyway, you can buy it from https://www.steinberg.net/spectralayers/
