I bought the license and I need help on uploading a large file up to 500mb limit..

    Basically, I got it to work on less files up to 40-50mb to upload but when I started

    uploading 350mb..I get an error "unable to find file .... in /public_html/temp when

    the upload ends... I got the php.ini settings and folder permissions set the way it should

    but still no luck....Need help... Thanks
