i cannot register my CorelDRAW Graphics Suite 12 on corel.com

the thing is that i had to format my computer and now after i install the corel draw when i click on register a IE window appears with corel.com on and it says that corel draw 12 is not supported anymore. Also, i would like to ask you guys if i can upgrade it to an x6 or x5 version by buying an update license. 

Please help me i need it really fast.

Thank you in advance.
