Cloud or not to Cloud? Subscription question from past user

[Guest]

I can't seem to get my question answered definitively.  Used to be a registered user of InDesign CS5.5.  Haven't used the program in a while.  However, recently upgraded to a new PC with windows 10 installed.

Will my older version of InDesign work if I install it on Win 10?  Or will it just crash?

If I buy a new version of InDesign to work with Win 10 do I really have to spend $200 or so a year to get a copy?  I'm just a casual user at this point, so I don't understand why there isn't a cheaper way to buy it?  And if I spend the $200 for the first year, and don't renew it.... do I lose access to the program or just support?  Confused?!  How come as a registered user, I'm not offered any discounts?

Is there a big learning curve to go from CS5.5 to go to most current, Win 10 version?  Or will I be pulling my hair out?

Thx for any answers.

you can expect some problems with cs5.5 but you can probably get it to install and work satisfactorily.

the current version of id (cc 2017) does not require significant learning unless you want to use the newer features that were not part of cs 5.5
