Adobe CS6 randomly asks for reactivation (Deployed using AAMEE 3.1)

Hi All

We've deployed Adobe CS6 Design and Web Premium using AAMEE 3.1 to about 500 workstation across our school campus.  However, we're having a really weird issue where either the licensing screen will randomly pop up asking for reactivation (7 days) or the program requested will just fail to run.  If I try to reactivate using the wizard onscreen it says I don't have a valid internet connection.  This causes a lot of frustration for our users (and me!!)

The only work around I found to it is to re-serialize using a serialization package made with AAMEE.  I'm considering adding it to a start-up script to re-serialize every PC when they are booted up each day but it it seems ridiculous to need to do this.  I thought AAMEE removed all activation checks and prompts, this doesn't seem to be the case here??

I've had a look around the forums and while there are similar issues I haven't found a resolution to this, any help/suggestions would be much appreciated!
