Sprung for Acrobat PDF trial. To burn to a CD, do you have to save to Cloud first?

[UTUSN]

Am totally new to it, besides indescribably Low Tech.

So this is pages saved to a disc. I didn't create the disc. I made changes with the CD R in the drive and tried to Save to the same disc: No.

It wanted me to rename and Save somewhere else (who knows where). So, not wanting to lose the changes, I Saved to the only place I could find, the Acrobat/Adobe Cloud.

I'm thinking the Cloud version can now be Saved onto a *BLANK* disc, no?

If so, but now I want to make changes to the Cloud version, so am first going to make a disc of the first changes, then try changing the Cloud version for another disc.

Or, can changes to the Cloud version be Saved (in the Cloud) for a new disc?

Or, will changes to the Cloud version mean going through the rigmarole of renaming and another version?
