BRIDGE - can't verify your subscription

Last week I updated to Bridge 11 and uninstalled the previous version. On Saturday the clocks went back an hour in the UK.

Since Sunday morning I have been getting the above message (see attached image) every time I open Bridge.  I get the same on 2 different computers.  I have a relialbe internet connection (chrome browser, email working fine) lightroom also working ok, I have cahnged the clock setting as suggested.

I have also signed out of all Adobe apps in Bridge and then re-signed in.  No change.

I should add that if I just close the dialogue box Bridge does seem to work fine.  

Any suggestions to solve this problem.
