Purchased PRO But Still Prompted to Purchase AGAIN

I purchased the PRO version with license key: sk_i%?NKDzde.6%+GsZe#B#znIdWs%y5

Followed instructions email me to install and activate yet this is not picked and I am still being prompted to upgrade! Please resolve as it is annoying to have purchased and yet still be instructions that do not correlate with that the options that the system gives you. There is no option to add license key on my wordpress site.
