Typesafe Activator 0.3.0 Failed to bind to: /127.0.0.1:8888

Question

I'm trying to use typesafe-platform and when I run command activator ui I get this Exception:

C:\activator-0.3.0>activator ui Found previous process id: 7552 Play server process ID is 3828 [info] play - Application started (Prod) Oops, cannot start the server.

But there is no process using 8888 port.

I'm Using Windows 8 Pro with JDK 1.7 Update 25 64 Bits

I'm using Play 2.1.3 in PATH Evironment Variable

Anyone had this problem?

Thanks

You can now override the default port using the http.port Java param. So to launch the UI on port 9999 do:

activator -Dhttp.port=9999 ui
