the new xara version you have to pay for every year or it stops working [reverts to a demo mode which, unlike trial mode, dosn't really do anything useful]

the plus side is that it is updated regularly and you get features like the modular websites; the magix version gets updated once a year, and is way behind the curve; but then if you don't need the new things you can save by not updating; you do not need to move to the new pro+ version, you can always try the trial it is a completely seperate program; if you install that and let it lapse you may get offered a discount to keep it

I let mine lapse

was a year or two now since it was launched; someone like acorn probably has all the details at their fingertips....
