We use a licensed version of Surfcontrol on BM3.7, NW6.5 SP5. The license is due to expire at the end of the month but the server is due to be scrapped by early December. What will happen when the Surfcontrol license expires? Will it:

a) just deny us any further database updates
b) revert to only the 7 (?) original 'free' filtering categories
c) stop working altogether?
