Can you change the quantity to 1?

You should be able to remove 1 of them, the full one not the upgrade, to get it at the correct price.

If you let your subscription expire, the programs will still work. However, you will need to download and keep the install files as you won't be able to download any updates from your downloads page after that time.

I'm not sure about the second part of your questions.  What theme?  

One would think I would know all about this after 7 years here and have never let my sub run out. However now I'm not sure and have to ask. 

I thought if you had your programs downloaded along with the serial numbers they would always work. I know if your sub runs out you can't download from the store or manager. What I did believe is if you did let your sub go and say you get a new computer or just format the one you have you could install the latest version one saved put in your serial number and it would work. 

What you are saying is you can install it but it won't activate. If it won't activate it I can't see how it will work. You can install many outside programs that you purchased but in order for them to work or activate you have to put in the serial number. Please advise what I'm missing here?

Thank you for your reply.
