I have a couple of EXPs and while I am not an expert, in my opinion you have a fine kite that will give hours of fun.
As has been pointed out, setup and configuring the line lengths including leaders is a key to success, and I defer to the other comments in that regard. (Hands on help is useful if you can get it, but flyers are often few and far between.)
As far as wind: I, too, fly in shifty (with an ‘f’!) inland winds and in my experience the sweet spot of winds for a current EXP, until one gets more familiar, is approx 5/6 mph *minimum* to 9, maybe 10 mph max. The actual range of the kite is much broader, but will complicate things for you early on. You want the ‘drive’ the wind provides, but not too little or much. You have enough other issues on your hands. (The lower end can be further extended with a lighter frame.)
It may be that you are familiar with wind from other kiting, but if not, and if it assists, there are simple charts which may help give a visual on winds that you might encounter, such as the one below.
Hang in there. Keep at it. And the 3 Ps: practice. Practice. Practice.
