When I go to my addons in FSX there is no box but if I click on addons the etailer box comes up but it is for Cloud9 Orlando. So how do I activate my product XPOI?
I'm not sure I understand what do you mean with "box" ( dialog box, maybe ? ) but, if you see a prompt to activate Cloud9 Orlando, it seems you clicked on the "Register Serial" without selecting the product to be activated first.
As you can see, you can activate man different products with the Addon Manager, from different developers. If you don't say which product you want to activate, the Register Serial will assume the first product of the first developer in the list, which is already selected by default, and it's Cloud9 Orlando.
If you want to activate XPOI, since it's an Fsdreamteam product, you must select Fsdreamteam from the developers list, and then XPOI from the products list, so "Register Serial" will know which product you wanted to activate, amongst the many available.
