Activation Problem

[Nextec]

I've got a little problem and I hope that anybody can help me out.
I bought Sylenth1 and installed it on my Mac at home. I activated my second license on a PC in another town, where I also produce really often. On this PC I installed iOS but switched it back some days ago. Now I have the problem that my second license is activated on a "Mac" that doesnt even exist and I cant deactivate it anymore.

Is there a way I can get this license slot back? :/

Thanks for your answers!
