What version of DW were you using previously?
A lot has changed, and the most recent versions are a bit buggy. As a CC subscriber, you're not forced to use the latest offering though. You can have an older release (like CS6 Cloud) installed at the same time as the latest version so you can work with something more familiar while getting up to speed with CC.
To do that...
1. Open the CC Desktop App
2. Click the Apps tab
3. Click the small triangle next to DW's button
4. Choose "Other Versions"
5. Click and install CS6
You can actually have all versions on the list installed on the same machines at the same time under a single subscription, they just won't run concurrently.
