Photoshop and Premiere ask me for serial number

Question

I have the one year Creative Cloud service (so no serial number), but both for Photoshop and Premier I have these messages saying that I'm using a test version (I downloaded both from the Cloud) and that if I don't provide a serial number I won't be able to keep on using them.
I'm using Mac OS X 10.7.5 and my Creative Cloud service started 5 weeks ago.

Hi there,
    Sorry for the inconvenience caused to you.
Follow the below instructions and check if they would work:
1. Once you launch the software, it says to "License this software". Select this option and enter your credentials. Check if this works.
2. If not, disable Firewall & anti-virus and try the first step.
3. If the issue persists, you need to check the Host files. Firstly copy paste this URL: https://lm.licenses.adobe.com on a new browser and see if you get a "Congratulations......" message. If not, follow the below steps to edit the Host files:
Windows
Locate the hosts file.
Click Start, click Run, type "%systemroot% \system32\drivers\etc" and then click OK.
Right-click the file and select Open. Select Notepad for the application to open the hosts file.
Save a backup of the file. Choose File > Save As. Name the file hosts.backup and click OK.
Look for any entries that refer to activate.adobe.com and delete these entries. For example, 127.0.0.1 activate.adobe.com and delete this entry.
Save the file and close it.
To create a default hosts file, see http://support.microsoft.com/kb/972034  for instructions.
Mac OS
Open a Finder window. Choose Go > Go To Folder.
Type "/etc" (make sure that you are is logged in as an administrator).
Select the hosts file and open it.
Look for any entries that refer to activate.adobe.com and delete them. For example, 127.0.0.1 activate.adobe.com and delete this entry.
Save the file and close it.
Please let us know if these instructions work.
