Hello,
You can read about license keys in our
F.A.Q., see section 4. In brief, after your purchase we need to make sure your payment is verified. Usually it takes several days (2-3). For this short period you may generate temporary 3-weeks license in member area. The product will work correctly and have full functionality with this license but you could use it for limited time. When your payment is verified may generate full license key in member area. Regarding issue with results limit, what plugins you use, what happens when results contains more than 100 rows?
Regards,
ARI Soft
