Changed wireless card

I found the file MarkCheli suggested when getting an "Invalid Host" error on start up of Creo2

" If you see "Invalid Host" in the Warning Message List dialog box then try this guide...

This explained the reason I was having this problem. The software is linked to the wireless card. As I had to put in a new wireless card I no longer have access to the card I was using when the software was installed the first time. Can you tell me what I can do fix this problem?

Thanks for any help
