If you are being prompted to enter your serial number when opening your actively subscribed Creative Cloud application then there maybe missing account information. Please see Creative Cloud products prompt for serial number on launch | CCM - http://helpx.adobe.com/creative-cloud/kb/ccm-prompt-serial-number.html for additional information.

A language conflict of your operating system and your CC licence could also cause problems. You could check that the apps default language setting in the application manager is international English before you start to download the new apps.
Great point Kysysmys73 we do offer an English only subscription option in the EMEA region. If you have purchased this subscription then please ensure that your language is set to International English.
I purchased my CC subscription in May 2012 through CDW as it was a non-profit license. I have upgraded and installed the newest CC app manager. When I go to license my Adobe CC products with the serials from my Volume License site the keys are not valid. I have chatted with Adobe support twice. I have called CDW more than three times. No one seems capable of resolving this issue. Appareanlty my account was established as a Team Ready and needs to be migrated to a Creative Cloud for Teams. How do I do this? I am totally helpless and spending WAY too much time on this issue...PLEASE SOMEONE HELP ME!
I have spent hours trying to get help with this problem. I have followed all advice concerning verification of my account, adress etc but the problem persists. Adobe AppManager keeps asking for a serial number. No one at Adobe in Sweden or else where seems to be able to advice me on how to fix this extremely irritating problem.
Carstenluhrs and Kenyongerbrandt please see the network configuration documentation in the original post. If you are being prompted for a serial number then it is likely that your computer is not able to contact our activation server. There should be no need to enter a serial number for software included within the subscription to Creative Cloud.
I've followed those steps and every thing is as it should be. I've finally made some contact with an Adobe rep at the reseller, but this issue is still not resolved. It appears that migration from Team Ready to CC for Teams is not as fluid and straightforward as thought. Is anyone else experiencing issues with this? Really bummed I can't even download LR5 at this point.

Thanks Kysmys73 for a solution for a very frustrating and time consuming error. I think it's a major fail from Adobe not to make clear these required language setting. Not upfront, when you order the Adobbe CC licenses, not when installing. Worse: other languages (like in our case 'Nederlands' - Dutch) are valid options in the menu. And finally not by giving an clueless error message after installing: 'this software will run in demo mode'.
Allthough it's nice Jeff A Wright gives kudo's to Kysmys73, the quoted answer is not correct and will again lead to frustration. It's NOT 'the' or 'your' language that should be set to International English. It is, as Kysmys73 points out, the App Language: setting in the Preferences of Adobe Creative Cloud desktop, or Adobe Application Manager. Choose the gear -> Preferences-> second tab which is called Apps.
So you don't have to change your OS language, just change the language setting in de Adobe CC download program. And make sure you do this BEFORE you download the other Adobe CC programs.
