Can'not activate the product

Just bought the GHD from the X-Plane.org store (like 15 minutes ago). When I try to activate the product I recieved the following message in my e-mail:

I removed the key.reg file, as said in the first topic, entered my e-mail and the serial and recieved the same e-mail.

Just did like the instructions, opened the default 747, plugins, ground handling, registration. Put my e-mail and the serial key provided by the org.
