Hi, I purchased the very last box on the shelf of Easy VHS to DVD 3 Plus from a retail chain but it had no disc which i was made aware of before purchasing. Was told I could download software online instead. I don't have a valid serial number it seems so how do I do this? I have the hardware but obviously need the matching software. Otherwise I'll be taking it back. I knew the box had no disc but it was the last one and they couldn't find it so they assured me I could download it online? Is this in fact true or not? i have the receipts so can bring it back.
