Will Adobe CS5.5 Work on Yosemite?

Question

I was wondering if anybody who has downloaded the Yosemite update and uses CS5.5 software, if your software was able to work?  I really need to know because  I got the CS5.5 creative suite (at the student price and version) when I was a student in college, but I had received a faulty disc that didn't work so both times I've had to install it by calling Adobe Tech Support (since my Macbook Pro Graphics card went out, thus replaced it with my current Macbook Air, Mid 2011) via a download code they sent me both times.
I am an artist and have a degree in Graphic Design, so having my Adobe programs work is very important to me!  It's also my only source of income at the moment via art commissions.
These are the Programs I need to know about
*Flash CS5.5
*Ilustrator CS5.1
*InDesign CS5.5
*Photoshop CS5.1
My current setup is OS X 10.7.5 Lion and everything works fine.  I refuse to upgrade my Mac unless I know my programs will work or until Yosemite fixes the glitches with the Adobe programs (according to reviews I've read.. most negative thus I'm really scared to upgrade).
Please help!

A partition is part of the space on a hard drive. Using Disk Utility on an empty drive you can, during the formatting operation, set up two or more partitions. Each partition will appear on your desktop as a separate drive and can be used as such. You can save to each, open files in each, eject each, mount each, as though each was a separate physical drive. Partitions are a tidy way to keep files separate from others not related to them: such as the installation of a complete operating system; backups of your current system; files etc.
I'm not sure but I don't think that complex applications like Adobe's can be backed up as stand-alone applications. This is probably because when they are installed the installation involves putting code into the bowels of the Operating System, and making a copy of the application would not copy that code. Obviously, Adobe make sure that their software cannot be copied simply, for obvious reasons.
I think (only think) from an experience a few years ago that Adobe keep a record of a person's purchases and subsequent upgrades of their software, and you might be able to contact Adobe (their Chat line worked well for me a year ago when I upgraded from Photoshop and Indesign CS5.5 to CS6) and on giving them details they might allow you to re-download their application and give you an activation code.
When I upgraded to Yosemite yesterday I simply ran Apple's installer obtained from the App Store. This installed Yosemite without interfering with any documents, application, utilities, music, images, emails etc. so I was able to use my iMac right away as normal. I have successfully upgraded the OS like this from Lion to M. Lion, to Mavericks, to Yosemite, relying on the OS installation not corrupting any of these files. Worked so far.
More generally you might like to consider getting a backup utility like Carbon Copy Cloner or SuperDuper. Using CCC my iMac does a full cloned bootable backup of my whole system at 4 am every day on to a USB 2 external hard drive. If I get corruption (very rare) I can just boot up (restart) on the CCC clone as the Startup disc (see System Preferences) and get back to 4 am in about 10 minutes, or use CCC to clone the backup clone on to the internal hard drive in about 20 minutes.
Good luck.
