I bought rankerx yesterday, today I am facing login issue. I tried contact them via messenger. they didn't reply, then i send mail to support. They simply send a message like "try again". I tried many times, but it is not opening. it shows error like " there is currently running instance of the software elsewhere. Please deactivate this before continue." I am using this software in my device only (one only). They stole my money and they didn't respond. Is any other solution is there?
