WPRobot 3.31 Nulled version not working

Hello friends!!
I am using WP Robot from last 3 months, it is null version. of 3.31. Last day I clear post history in WP Robot, It again ask me e.mail address, I del this version & install nulled 3.2 then 3.31 (as I do during last installation), but got the error WP Robot could not installed, or Please go here to finish the installation of WP Robot first.
I deleted the MYSQL tables & then again install following the same procedure but got same result of issues.
I do it for several times .... but effect less result

wprobot is on the no share list, discussing the proper cracking or nullifying of the software on the forum is prohibited.

Buy it. Most nulled seo tools don't work properly anyways, you'll be saving yourself time and money and getting yourself proper support by supporting the software. If you've used it 3 months and can't afford to buy it, the nulled version wasn't performing for you well enough anyways, maybe a proper installation would work better.

I also use same WP robot on other wp blog today, it works fair with me

Using a null'd version and expecting it to work perfectly? (if not backdoor'd) lol. take care.

I find answer of my question on WP ROBOT forum, it is faced to my purchased members of the WP Robot,
W3 total cache .... disable it & got back again
