Creative Cloud error - reinstalation needed every day

For the last 3 months, more and more problems with CC occur. Last weeks almost every day started like this - after turning on the computer, CC comes with a note - "the app is damaged, it needs to be reinstalled." This takes about 10 to 15 minutes of my working time. After that, the CC seems to be upgrading - another 5 to 10 minutes. 
After these operations are finished, I open any app (Photoshop, Illustrator, Indesign...whatever) and I got another error note: Your subscription status cannot be verified (I have to say, I'm not offline)...next in line is another note: "We're sorry, but there was an error in the product, we need to close it"

There are also problems with Typekit synchronization (fonts do not sync). Please, can you do something about it?  These problems take too much of my working time.
