Can't install CorelDraw X7

Hi all,

I am trying to install X7 on my Win 8.1.
I connect to the internet through a WIFI. (Netgear Aircard)

The program wants to validate the serial number before it will proceed with the installation. Even though I am connected to the internet, it keeps telling me that I'm not and won't go any further. Frustrating to say the least. I have tried more than once with the same results.

If Paint Shop Pro would simply print oversized pictures over multiple sheets of paper like it used to do in older versions, I wouldn't even need Corel Draw at the moment. I have large line drawings that I need to print out and the only way I've been able to do it is to open my PSP files in Corel Draw and use its print function to print the oversized pieces. Was able to use it on my Win 7 when I was still on dial-up (sadly, not that long ago) but I've never been able to install it on Win 8 with the WiFi.

So 2 pieces of advice would be really appreciated:

1) how do I get Corel Draw to recognize that I am online and proceed with the installation?

2) Better yet, is there any way to get PSP to print oversized, multi-page drawings?

Or is there some other app that I can use.

Thank you!
