ProStitcher Tablet

I have an Avante with the ProStitcher Premium. My machine is only about 2 years old, and I would like to upgrade to a Forte. I want to use the same tablet because I simply cannot afford to buy the software again with as expensive as it is. Please tell me, honestly, if my computer from the Avante can be used on the Forte, and be honest. I don't want to get cornered into buying the extra simply because HQ wants to make more money. 

Also, I notice that when I install updates for my PSP, I do have the option of which machine I am installing it on, so to me that means the possibility is there. 

Any help is appreciated,

Bridget
