TWC installed today, brought CableCard but no tuner adapter!

When I called them back early last week when I found out I needed to make sure they are including a tuner adapter the told me they added it to the order for me. Fast forward to today and the installation guy told me it was on the order for him to install but they don't send those with the drivers, they are mailed to our home before the installation date. The rep on the phone said the install guy will have it. They shipped one out today and I should have it by the end of the week.



Question, can I just install the CableCard without the adapter and will I get any channels (at work now so can't try it) or do you need the adapter to get any channels?
