70719 Traffic Exchange Fix URGENT

Hi All, I just started a traffic exchange [login to view URL] And all of a sudden the scripts do not work any more, and MySQL is overloading my server (crashes every 12-15 hours) The programmer that delivered it has no time, so I need an expert to get into the PHP / MySQL scripts and get the problem solved. Also, the site is LIVE so I can not have any more problems while debugging this. We can work on this though, see what is needed etc. Payment through Scriptlance / Stormpay / [login to view URL] - you choose Kind regards, Quickjob
