Could you please confirm the version of Lightroom and Photoshop that you are using?
Are you not able to get the Lightroom adjustments when you take your images to Photoshop from Lightroom?
use the latest version of Creative Cloud, version 6, it does not work the 'editing' for eleaborare the photos in photoshop
Still could not understand your issue.
Please share your complete workflow steps and the exact issue.
Lightroom version: CC 02.01.2015 
License: Creative Cloud
Operating System: Mac OS 10
Version: 11.10 
I process a raw file in Lightroom, then clik right on 'modification', the file is opened in Photoshop or if you open does not report the corrections made on lightroom. To transfer the correct file in Lightroom I use 'Export'.
This does not allow me to come back with the file ligtroom for new corrections.
Thank you for the update.
When you access a raw file in Photoshop, the Lightroom adjustments are not carried over by default.
However, you might want to try the following steps :
1. Go to Lightroom Preferences> External Editing
2. Click on choose next to Application under Additional External Editor and add Photoshop application
3. In Lightroom, right click or control click on any image and choose Edit in Photoshop and check if you are able to edit in Photoshop with Lightroom adjustments.
I performed what I said, but it does not work since the last update of creative cloud
Who should I contact for more details
