Hallo,
 
I buy raptur last at july. Playing it with abelton live 9 lite without problems.
 
If I open it some days ago rapture ask me for registration. It is the same PC and I don’t change anything (hardware and software) Win 7 SP 1. If I enter my code and click Complete it says: "Registration code invalid. … 30 days" If I look for the Program is says “rapture microhost”.
 
Start with admin. Every time I start rapture plugin ask for this registration.
If I reinstall und install again same problem. If I open in in Musik Creator same problem.
 
Please help!

Usually this is the result of running a user with admin priviledges instead of actually running the program as administrator by right-clicking on the program and selecting the "Run as Administrator" option.
