activation Coreldraw X5

Hello!
I'm from Poland.
I dont know what to do and where I should write or call.
I made reinstallation of computer ..to Windows 7 in enterprise. 
I installed the Coreldraw X5...but I didn't have a cd ..I installed from the web site.I have a key in a book but no cd :-(
I couldn't make activation...maybe some of restrictions in the enterprise policies. 
I bought the support service ..but I tried to input the code from an order ...but the button of activation is a grey..I couldn't use the software and the term of 30 days was ended. Please help me. 

I try to use a PIN code which I got after registartion and this code is invalid when I tried to make a question in Support 

Help !!
