I went ptvupgrade looking to purchase InstantCake to upgrade my Humax DRT400.  This is the site.  http://www.ptvupgrade.com/products/instantcake/

It does not list DRT400 but does list Humax T800.  I had read oin the threads that DRT400 and DRT800 Software were the same and since it was the only listed, I assumed it was correct.  Created several disks with no luck before Lou pointed out to me that the correct site was http://downloads.ptvupgrade.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=ICAKE2-S2SA-DVD&Category_Code=

I have no idea how to get there other than this link as when I go to ptvupgrade.com click on producst and services and then Instant Cake, I get the first link that does not list DRT400.

That is a long way of saying, can I get a trade?  Do I have to buy the software again?
