Thanks Jon, I do realize that; however, when I had the cloud in 2013, even though I had copies in my applications folder, twice Adobe turned off all my programs, once for insufficient funds with no warning, this was a friday, I couldn't make a deposit until Monday, to be credited to the account on Tuesday. I couldn't do any work for 4 days. Then at the end of the year when I was happy to go to the $49. per month system, Adobe somehow glitched for a week and I had no Adobe for a week. At this time I decided that after twice, the cloud wasn't for me. I work on photography, publishing and or design every day, I can't be waiting for someone to say it is ok today to use your stuff. 
I reluctantly again had to go to the cloud for the photohop/lightroom package because of a new 46 megapixel camera that forced me into a new computer. As soon as the bumps get smoothed out I'll be switching to Capture One. I haven't yet determined what my next web design program will be.
