I reformatted my hard drive / changed something in my computer and now ConQuest/Mogul/registered Mercury* features doesn't/don't work


*Some of the advanced features of Mercury require activation, which is only possible for CSD software suite subscribers.

The CSD software suite licensing mechanism relies in part on some data derived from your computer to create a unique identifier. If these change, then this can fool the CSD software suite components into thinking that you have installed them onto another computer.

Please contact us with details of the computer that is affected and we will arrange for the appropriate licences to be freed up.​
