Someone posted this on the Steam forums - it's from the Origin help section, I thought some of you might find it interesting.
"QUESTION
I've received an error message on Origin, what does the error mean?
ANSWER
You may receive one of the following error messages if you have reached the maximum amount of times your game can be downloaded through Origin:
For security reasons, you are allowed # concurrently active licenses. This limit has been reached. Please wait until one of the other licenses auto-expires, then try again.
License response error: '78008,Max machine lifetime entitlement met:#
Error: 10000:78008
Every time the download button is clicked, a download count will be added to your lifetime total. If you have installed your game via Origin on more than three computers within a ten day period, you will need to wait until the first installation expires.
Note: Re-installing your operating system, or interrupting a current download, will count as a new computer installation.
If you have reached your download limit, click Contact Us and include your account name, the title of the file or game you are downloading, and a brief description of the issue."
