Trying to install kleo, error code says I haven't purchased

Hi there: I installed Kleo theme once, and goofed it, so I deleted the installation and even the database. I started by re-installing wordpress. Now I’m back, working to install, usin gmy themeforest username and an assigned api key and am getting this error code: ERROR: It seems you have not purchased the theme from the added account. Please check the credentials provided!

Any suggestions?

HI, try to regenerate the API key and use the new one. Please use our dedicated support site for any theme questions
