Creative Cloud seems fundamentally broken?

Hi,

I've been using CC for many years now, and I'm not sure what it is, but it just seems like it is completely broken for me and does not improve with updates at all?

My problems are:

1. I constantly have updates available, no matter how many times I update my apps.
2. Programs like to crash, causing the 'CC needs to repair or uninstall to work' error message.
3. Fonts do not sync. 
4. Apps uninstall themselves.

I have tried everything I've found on the internet to fix the above errors, short of completely wiping my Mac. (I do not want to do this as it means we will have to call in the IT Engineer to connect us all back up to the servers, £££).

I pay £50 a month for this service. Please just make it work!
