After googling and learning (and much frustration) that Adobe canceled the Flash Prfessional Animation tools especially the CS5.5 version in which I still work, my issue is the following: (Leaving aside the rendering qulaity and solutions), I use the CS 5.5 for my animations since I have my animation heroes (4 months of full time work of finished symbols, turns, tweens movieclips, movements etc...) in that tool.
On my older computer I used to have the CS5.5, but for reasons of stories too long for this post, I now only have a laptop with Windows 10 and I would like to install one of the Adobe tools in which I cold work on my animations (but transfer them first succesfully). I see a posssibility in installing Animate on my laptop, but I dont know if it will open my old CS5.5 work. If I install the CS5.5 than there are the rendering issues... (Even if only the graphics without the movements survive in a newer tool, would be survivable for me...) I'm a little lost.
I would sincerely be grateful for your help.
