Sage Line 50

Ver 3.0.15.277

I’m using Sage Line 50 (ver 2008).
All transaction times are geatly extended, when Defence+ is enabled.
Ex. edit customer normally less than 1 sec with Defence+ disabled.
Goes to +25 sec with Defense+ enabled.
Have ensured app is “trusted”, to no avail.
Any help would be appreciated.

Thanks
