Can you still run version 14?
If so the WIBU key is still being recognised but may not have upgraded properly so check with the license activation tool again.
If 14 is not running then try plugging the WIBU key into another USB port.
Maybe try that anyway.
And when in doubt remove the key and restart your machine then replace the key.
A simple restart can sometimes do wonders.
